Lemon Posset
Lemon posset is a classic British dessert made with just double cream, caster sugar and fresh lemons. The Thermomix TM7 grinds the lemon zest with sugar for an intense citrus flavour, then heats the cream gently to a precise temperature, giving a silky, velvety set without any stirring effort.
About this recipe
Lemon posset with the Thermomix TM7 is one of those rare dessert recipes that tastes luxurious yet requires only a handful of ingredients: double cream, caster sugar and fresh lemons. The secret to a truly exceptional posset lies in the flavour of the lemon zest, and this is exactly where the all-in-one kitchen machine shines. Instead of grating zest by hand, the TM7 grinds the zest together with part of the caster sugar until the oils are fully released, creating an intensely aromatic citrus sugar that colours the entire dessert. The gentle heating of the cream with precise temperature control means the sugar dissolves completely without the mixture boiling over or catching on the base. After adding freshly squeezed lemon juice, the classic acid-setting reaction takes place as the posset chills, firming into a velvety, spoonable cream. Serve this elegant dessert in pretty glasses at a dinner party, Sunday lunch or any festive occasion, topped with berries or shortbread biscuits for contrast.
Preparation tips
- Use unwaxed lemons for the zest, since the TM7 grinds the peel directly into the caster sugar and any wax coating would end up in your posset. Roll the lemons firmly on the worktop before juicing to release the maximum amount of juice.
- Pour the warm cream mixture into small glasses or ramekins through a fine sieve to catch any pieces of zest, ensuring a perfectly silky posset. Leave them to cool completely before transferring to the fridge to set for several hours.
- For a playful presentation, top each lemon posset with fresh raspberries, a shortbread biscuit or a small spoonful of lightly whipped double cream. A tiny pinch of ground ginger echoes the optional spice already in the recipe.
Recipe variations
- Lactose-conscious variation: replace the double cream with a thick plant-based cooking cream suitable for heating, and use caster sugar as normal. Note that the setting relies on the acid reaction, so chilling longer helps achieve a firmer spoonable texture.
- Festive winter variation: increase the ground ginger slightly and add a strip of unwaxed orange zest when grinding the lemon zest with the sugar, creating a warming citrus-spice posset perfect for Christmas dinner, garnished with candied ginger.
