Fresh Tomato Sauce and Passata with the TM7 | Thermomix TM7

<h2>Preserving the Essence of Summer</h2>
There is a specific moment in late summer when the kitchen naturally transitions. The air grows crisp, and the gardens, farmers' markets, and grocery store aisles suddenly overflow with crates of deeply red, sun-ripened tomatoes. The smell is intoxicating, earthy, and sweet. For centuries, home cooks have dedicated these late summer weeks to the beautiful ritual of preserving this vibrant produce, ensuring that the taste of August can be savored on a cold, snowy evening in January. However, traditional tomato sauce and passata making is notoriously labor-intensive. It requires hours of standing over a hot stove, endless stirring to prevent scorching on the bottom of a heavy pot, and the tedious, messy task of passing boiled tomatoes through a manual food mill.
Enter the Thermomix TM7. As your personal kitchen assistant, the TM7 completely revolutionizes the art of tomato preservation. With its precise temperature control, incredibly powerful motor, and the sheer genius of its integrated reverse blade and simmering basket system, the TM7 takes the sweat, tears, and endless manual labor out of sauce making. Imagine achieving the silkiest, smoothest passata or the richest, chunkiest slow-cooked marinara without ever having to stand over a hot stove, constantly scraping the bottom of your pan. The TM7 stirs for you, cooks at the exact temperature required to intensify flavors without burning the natural fruit sugars, and can even mill your tomatoes to perfection in seconds. In this comprehensive guide, we will explore how to harness the full potential of your TM7 to fill your freezer with the glorious colors and flavors of summer. We will cover the best tomatoes to use, how to prepare them, a master recipe for smooth passata, a robust recipe for a hearty tomato sauce, incredible flavor variations, and the most common pitfalls to avoid. Get ready to capture sunshine in a jar.

<h2>Section 1: Choosing and Preparing Your Tomatoes</h2>
The absolute foundation of any great tomato sauce or passata is, rather obviously, the tomato itself. When you are preserving, you are concentrating flavors, which means any imperfections in the raw fruit will be magnified in the final jar. You must start with the highest quality, fully ripe, and vibrantly colored tomatoes you can find. This is the time to visit your local farmers' market, accept that overflowing basket from your green-thumbed neighbor, or buy a bulk crate from a trusted local farm. But what are the best varieties to use in your TM7, and how exactly should you prepare them for optimal results?
When it comes to passata, where a smooth, thick, seedless texture is the ultimate goal, plum tomatoes are undisputed royalty. Varieties like Roma, San Marzano, or Amish Paste are ideal. These specific cultivars are prized for their dense flesh, remarkably low water content, and very few seeds. Because they contain less moisture, they require significantly less reduction time on the stove, which ultimately saves you hours of cooking time and ensures a more intensely flavored passata. If you are making a rustic, chunky tomato sauce to serve over hearty winter pastas or use as a pizza base, you can absolutely afford to be more flexible and creative with your tomato choices. A vibrant mix of juicy heirloom tomatoes, sweet cherry tomatoes, and classic beefsteak tomatoes will yield a wonderfully complex, sweet, and slightly acidic flavor profile. Do not be afraid to mix different varieties together; the TM7's precise cooking capabilities will marry the different flavor notes beautifully.
Before any tomato goes near your brilliant TM7 blade, proper preparation is absolutely crucial. First, wash your tomatoes thoroughly in cold water to remove any dirt, pesticides, or garden debris. Remove the green stem core using a small paring knife or a specialized tomato corer. The most divisive step in the tomato preparation process is blanching and peeling. For a rustic, chunky sauce, you can choose to leave the skins on—especially if you are using organic tomatoes. The TM7 blade is so incredibly powerful that it will pulverize the skins entirely, incorporating valuable nutrients and color into your sauce. However, if you are aiming for a truly traditional, authentic, high-end passata, the skins and seeds must be removed to achieve that coveted, silky-smooth, luxurious texture.
TM7 Quick Prep Tip - Blanching Tomatoes: Instead of messing up multiple pots on your stovetop, use your TM7 to blanch! Place 1 liter of water in the TM7 mixing bowl. Cut a shallow 'X' on the bottom of your washed tomatoes. Place them in the Varoma dish and steam for 10 Min / Varoma / Speed 1. Plunge them immediately into a large bowl of ice water. The skins will slip off effortlessly in seconds.

<h2>Section 2: The Silky Smooth Master Passata</h2>
Passata is essentially the pure, unadulterated soul of the tomato. It is an uncooked or lightly cooked, strained tomato puree that forms the foundational base for countless Italian dishes, quick weeknight pasta sauces, and rich soups. Making passata traditionally involves a hand-cranked food mill, aching arms, and an incredibly messy kitchen. With the Thermomix TM7, you can achieve a passata that is actually far smoother and more refined than anything a manual mill can produce, thanks to the centrifugal force of the blade and the precision of the appliance. The TM7 allows you to extract every drop of delicious, nutrient-rich juice while leaving behind the bitter seeds and tough skins.
The secret to a perfect TM7 passata lies in the revolutionary design of the simmering basket. The micro-perforations in the stainless steel basket act as a flawless sieve, catching the seeds and bits of skin while allowing the perfectly smooth puree to pass through into the mixing bowl. This is absolute kitchen magic at its finest. You do not need to peel or seed your tomatoes beforehand, saving you hours of tedious prep work. Simply wash, core, and quarter your ripe Roma or San Marzano tomatoes.
Here is your foundational TM7 Master Passata recipe:
<ul>
<li>Quantity: 1.5 kg (about 3.3 lbs) ripe plum tomatoes, washed, cored, and quartered.</li>
<li>Optional flavor additions: 1 peeled onion cut in half, 2 garlic cloves, 1 large basil sprig.</li>
<li>Step 1: Place the quartered tomatoes (and optional onion/garlic/basil) directly into the TM7 mixing bowl. It is perfectly fine to fill the bowl up to the maximum line.</li>
<li>Step 2: Secure the measuring cup into the lid. Blend thoroughly: 1 Min / Speed 10. The mixture will become a vibrant, frothy liquid.</li>
<li>Step 3: Set the fine-mesh simmering basket over a large, clean bowl or a large measuring jug.</li>
<li>Step 4: Carefully pour the pulverized tomato mixture from the TM7 bowl directly into the simmering basket. Let gravity do its work. Use the back of a ladle or a silicone spatula to gently press down on the pulp and seeds, extracting every last drop of that beautiful crimson liquid.</li>
<li>Step 5: Discard the dry pulp and seeds left in the basket (or better yet, add them to your compost bin!).</li>
<li>Step 6: Wash and dry the TM7 mixing bowl completely. Pour the strained passata back into the bowl. Add a generous pinch of fine sea salt to taste.</li>
<li>Step 7: To pasteurize the passata so it keeps beautifully in the freezer (or pantry if properly canned), cook it gently: 20 Min / 90°C / Speed 2 / Reverse blade. The Reverse blade ensures that the passata stirs gently without crushing any remaining tiny fibers, while the precise 90°C temperature pasteurizes it without a rapid, scorched boil.</li>
<li>Storage: Let the passata cool slightly, then pour it into freezer-safe containers, leaving at least 2 cm of space at the top for expansion, and freeze for up to 6 months.</li>
</ul>

<h2>Section 3: The Rich and Rustic Slow-Cooked Tomato Sauce</h2>
While passata is the pure essence of the raw fruit, a slow-cooked tomato sauce is a beautiful, complex, savory symphony. This is the type of sauce that fills your entire home with a mouth-watering, savory aroma that instantly makes everyone feel comforted and hungry. It incorporates aromatics, olive oil, and a gentle reduction process that concentrates the natural sugars of the tomatoes, mellowing their acidity and creating a rich, thick texture that clings perfectly to a strand of spaghetti. The biggest challenge when making a thick tomato sauce on a traditional stovetop is the dreaded splattering—the sauce bubbles aggressively, popping hot tomato juice all over your kitchen walls and stove, and the thick puree inevitably scorches on the bottom of the pan, imparting a bitter, burnt flavor to the whole batch.
The Thermomix TM7 completely solves these age-old cooking problems. By utilizing the Varoma lid (or the standard lid with the measuring cup) and the integrated stirring mechanism, the sauce is contained perfectly. The precise temperature control means you can set your TM7 to simmer for an hour or more, and the automated blade will gently stir the sauce continuously. This continuous movement prevents the dense tomato pulp from settling and scorching on the bottom of the bowl, guaranteeing a perfectly even, deeply caramelized flavor profile without any bitter burnt notes. Furthermore, the sealed environment of the TM7 prevents messy splattering while still allowing just enough steam to escape through the measuring cup to encourage proper reduction and thickening.
Mini-Recipe: The Ultimate TM7 Rustic Marinara
<ul>
<li>Ingredients: 1 large yellow onion (cut in half), 3 cloves garlic, 50g extra virgin olive oil, 1.5 kg ripe, mixed tomatoes (washed, cored, and cut in chunks - skins left on is fine!), 1 tsp fine sea salt, 1 tsp granulated sugar (to balance acidity), 1 large sprig of fresh basil, and a dash of balsamic vinegar.</li>
<li>Step 1 (The Soffritto): Place the onion, garlic, and olive oil into the TM7 mixing bowl. Chop finely: 5 Sec / Speed 5. Scrape down the sides of the bowl using the TM7 spatula.</li>
<li>Step 2 (Sauté): Sauté the aromatics to release their flavors: 3 Min / 120°C / Speed 1. You will smell the incredible sweetness of the garlic and onion blooming in the hot olive oil.</li>
<li>Step 3 (Add Tomatoes): Add the chunked tomatoes, salt, sugar, and a dash of balsamic vinegar to the bowl. Important: Do not exceed the 2-liter maximum line on the bowl.</li>
<li>Step 4 (The Mill): To create a gorgeous rustic texture without skins, blend the mixture: 30 Sec / Speed 8. The TM7 blade will completely pulverize the tomato skins and onion into a perfectly textured puree.</li>
<li>Step 5 (The Slow Cook): Add the fresh basil sprig whole. Cook the sauce down to concentrate the flavors: 40 Min / Varoma / Speed 2 / Reverse blade. Note: Using the Reverse blade is absolutely crucial here, as it mimics the action of a wooden spoon, stirring the sauce without chopping the basil or acting as a blender. Place the simmering basket on top of the lid instead of the measuring cup to allow more steam to escape, resulting in a beautifully thick sauce.</li>
<li>Storage: Allow to cool completely, then portion into airtight freezer bags or containers and freeze flat for easy stacking in your freezer.</li>
</ul>

<h2>Section 4: Elevating Your Flavor Profiles - TM7 Variations</h2>
Once you have mastered the foundational techniques of the smooth passata and the rustic marinara, the Thermomix TM7 opens up an entire universe of culinary creativity. Preserving tomato sauce is wonderful, but preserving *flavored* tomato sauces is where you truly start to elevate your future weeknight dinners. By making small additions before or after the slow-cooking process, you can build deeply complex flavor profiles that will make your winter meals incredibly exciting. Let your TM7 do the heavy lifting of extracting and infusing these flavors while you simply drop the ingredients into the bowl.
One of the most luxurious flavor profiles you can create is a Spicy Roasted Red Pepper and Tomato Sauce. The natural sweetness of bell peppers pairs perfectly with the acidity of tomatoes. To make this variation, simply add two large, cored, and roughly chopped red bell peppers to the bowl during Step 3 of the marinara recipe. The TM7 blade will pulverize the peppers into the sauce. During the slow-cooking phase, add half a teaspoon of red pepper flakes. The result is a sweet, smoky, and slightly spicy sauce that is absolutely magnificent poured over grilled sausages and polenta, or used as a vibrant base for a shakshuka on a cold Sunday morning.
Another incredible variation is a deeply savory, umami-rich Roasted Garlic and Herb Sauce. To achieve this, take a whole head of garlic, slice off the top to expose the cloves, drizzle with olive oil, and wrap it in foil. Roast this in your main oven at 200°C (400°F) for 40 minutes while your TM7 is cooking the basic tomato sauce. When the garlic is soft, golden, and caramelized, squeeze the sweet roasted cloves directly into the TM7 bowl during the last 10 minutes of the cooking time. Add a handful of fresh oregano, thyme, and rosemary. The TM7's gentle reverse stirring will infuse the sweet, sticky garlic and woody herbs throughout the entire batch of sauce. This specific variation is perfect for tossing with fresh ricotta gnocchi or spreading over a homemade pizza crust.
TM7 Flavor Infusion Tip: When using woody, hard herbs like rosemary or thyme, always add them at the *beginning* of the cooking process. The sustained, precise heat of the TM7 will gently fry these herbs in the olive oil, breaking down their tough cellular structures and releasing their essential oils. Conversely, if you are using soft, delicate herbs like fresh basil, parsley, or cilantro, add them at the *very end* of the cooking time. High heat destroys the delicate, volatile oils of soft herbs. Add them right before you jar or freeze the sauce to lock in their vibrant green color and fresh, aromatic flavors.

<h2>Section 5: Freezing, Storing, and Using Your Summer Gold</h2>
You have successfully transformed pounds of fresh summer tomatoes into beautiful, vibrant batches of passata and rustic sauce using your TM7. Now comes the incredibly important step of preservation and storage. Proper storage is absolutely critical, not only to ensure the safety of your food but also to lock in that gorgeous, bright red color and the fresh flavor you worked so hard to achieve. If stored improperly, tomato sauce can easily develop freezer burn, absorb unpleasant odors from the freezer, or even expand and crack its container, leading to a massive, frustrating mess.
The golden rule of freezing liquids, especially tomato sauce, is to always leave adequate headspace. Liquids expand significantly as they freeze. If you fill a glass mason jar to the brim with tomato sauce and put it in the freezer, the expanding liquid will exert immense outward pressure, inevitably cracking the glass and ruining both the jar and the sauce. If you prefer to use glass jars for environmental reasons or to avoid plastics, you must ensure you are using true freezer-safe glass (like specific Mason or Weck jars) and leave at least 2.5 to 3 centimeters (about 1 inch) of empty space below the rim. Allow the tomato sauce to cool completely to room temperature in the TM7 bowl or a separate container before transferring it to the jars. Sealing hot sauce in a jar and immediately freezing it will create excessive condensation, leading to ice crystals and a diluted, watery flavor upon thawing.
An absolute game-changer for freezer storage is the use of high-quality, silicone freezer bags or vacuum sealer bags. These are incredibly space-efficient. Once your TM7 sauce has cooled completely, ladle it into the silicone bags, squeeze out every last bit of excess air to prevent freezer burn, seal them tightly, and lay them completely flat on a baking sheet. Place the baking sheet in the freezer. Once the bags are frozen completely solid into flat, brick-like shapes, you can easily stack them like files in a cabinet or stand them upright in a deep freezer drawer. This method maximizes your freezer space exponentially compared to bulky round containers. A standard freezer bag will comfortably hold exactly two cup-sized portions (about 500ml), which is the perfect amount for a quick weeknight dinner for two people. Furthermore, flat-frozen sauces thaw in a fraction of the time compared to frozen blocks in glass jars.
When the depths of winter arrive, utilizing your preserved summer gold is a total joy. To use your TM7 passata, simply thaw a bag overnight in the refrigerator. You can make a lightning-fast, vibrant pasta sauce by placing a thawed bag of passata, a splash of heavy cream, a handful of grated parmesan, and a knob of butter into the clean TM7 bowl. Heat it gently for 4 Min / 80°C / Speed 2 / Reverse blade, and toss it directly with hot pasta for a restaurant-quality meal in under five minutes. You can also use the thawed passata as a spectacular, fresh-tasting base for homemade minestrone soup, or reduce it slightly in a pan to create a thick, zesty dipping sauce for homemade mozzarella sticks. The possibilities are truly endless when you have the essence of summer waiting for you in your freezer.

<h2>Section 6: Common Mistakes to Avoid for Flawless Results</h2>
While the Thermomix TM7 is an incredibly intelligent, powerful, and intuitive appliance, it is still essential to follow certain fundamental rules of cooking and food science to ensure absolute perfection every single time. Even the most seasoned TM7 users can occasionally run into issues if they rush the process or ignore the basic physical limits of the machine. To guarantee that your tomato preservation journey is entirely successful, stress-free, and yields flawless, delicious results, here is a comprehensive breakdown of the most common mistakes home cooks make, along with the specific TM7 strategies to avoid them.
<ul>
<li>Overfilling the Mixing Bowl: This is, without a doubt, the number one mistake enthusiastic cooks make when preserving in large batches. The TM7 mixing bowl has a strict maximum capacity line clearly marked at 2.0 liters. When you are processing large, juicy tomatoes, they contain a massive amount of water and air pockets between the flesh. If you fill the bowl past the max line, the blade cannot effectively circulate the mixture. This leads to uneven blending, leaving large, un-pulverized chunks of skin and seeds in your passata. Worse, during the high-temperature slow-cooking phase, an overfilled bowl will bubble aggressively, pushing raw tomato up into the lid mechanism, the sealing ring, and potentially out onto your counter. Always adhere strictly to the maximum line. If you have more tomatoes to process, do it in sequential batches—it only takes minutes!</li>
<li>Forgetting the Reverse Blade Function: The Reverse blade feature (clearly indicated by the opposing arrow symbol on the TM7 screen) is your absolute best friend when making any type of sauce. When you are slow-cooking a rustic marinara, the goal is to mimic the gentle, sweeping motion of a wooden spoon stirring a pot. If you leave the blade on the standard forward setting during a 40-minute cooking cycle, the blade will continuously chop the tomatoes, eventually aerating the sauce and turning it a pale, unappetizing orange color instead of a deep, rich red. Furthermore, forward motion acts like a centrifuge, pushing solids to the edges and potentially burning them. Always engage the Reverse blade for any sauce that requires cooking or gentle stirring.</li>
<li>Incorrect Temperature Settings for Reduction: Understanding the TM7 temperature scale is vital for achieving the perfect sauce thickness. If you want a quick, chunky sauce where you want to retain as much water as possible, setting the temperature to 100°C is fine. However, if your goal is to create a thick, intensely flavored passata or rich marinara, you must encourage evaporation. The Varoma temperature setting is specifically designed to take the liquid to the absolute boiling point (around 114°C-120°C internally depending on density), maximizing steam production. To safely use Varoma for an extended reduction, you must remove the measuring cup from the lid and place the simmering basket upside down over the hole. This acts as a splash guard, preventing hot tomato sauce from splattering out while allowing maximum steam to escape, resulting in a beautifully thick sauce.</li>
<li>Neglecting the Sealing Ring: The silicone sealing ring located under the TM7 lid is a miracle of engineering, but it is highly porous and acts like a sponge for strong odors and colors. Tomato sauce is notorious for staining silicone a pale orange color, and if your ring has previously been used to make a strongly spiced curry or a pungent garlic soup, those flavors can easily transfer into your delicate, sweet tomato passata. To avoid flavor contamination, it is highly recommended to dedicate one specific sealing ring exclusively for sweet and neutral cooking (like tomato sauces, jams, and doughs), and a separate ring for savory, highly spiced cooking. Always wash the ring thoroughly in hot, soapy water immediately after making tomato sauce, and let it dry completely in the open air to prevent lingering smells and stains.</li>
<li>Skip the Sugar If You Don't Need To: Many traditional tomato sauce recipes call for a large amount of sugar to mask the harsh acidity of out-of-season, unripe tomatoes. Because you are using peak, late-summer produce and the gentle, even heating of the TM7—which prevents the harsh caramelization that sometimes makes stovetop sauces bitter—you often do not need much sugar at all. Always cook your sauce first, let it rest for a moment, and taste it before adding sugar. You may be surprised by how naturally sweet your TM7 sauce truly is.</li>
</ul>
