EQUIPMENT AND PREPARATION

Before starting, it is advisable to prepare everything so that the recipe is quick and fluid. These types of desserts work best when each ingredient is at the right temperature.

What you need

✔️ Thermomix

✔️ Butterfly to whip cream

✔️ Silicone spatula

✔️ Large bowl

✔️ Glasses or cups to serve

Previous preparation

Take the mascarpone out of the refrigerator about 15-20 minutes beforehand. This helps it blend better and become creamier.

The cream, on the other hand, must be very cold. You can even put the Thermomix glass in the refrigerator for a few minutes before assembling it if your kitchen is very hot.

You can also wash and prepare the berries in advance so that they are ready when it is time to serve. 🍓

DETAILED STEP BY STEP INSTRUCTIONS

1 Place the butterfly on the Thermomix blades. Add the very cold cream to the glass and whip for 1 minute to 1 minute and 30 seconds at speed 3.5-4. It should have soft or medium peaks to maintain an airy texture.

2 Remove the whipped cream from the glass and place it in a large bowl. Reserve in the refrigerator while you prepare the rest of the recipe.

3 Without having to completely wash the glass, add the mascarpone, icing sugar, lemon juice, lemon zest, vanilla extract and a pinch of salt.

4 Mix for 30-40 seconds at speed 4 until you obtain a smooth, homogeneous cream without lumps. If there is anything left on the sides of the glass, lower it with the spatula and mix for a few more seconds.

5 Pour the mascarpone cream into the bowl where the whipped cream is. First add a small amount of cream and mix gently to lighten the cream.

6 Incorporate the rest of the whipped cream little by little with enveloping movements using a spatula. This step is key to maintaining the airy texture of the mousse.

7 Divide the mousse into individual glasses or a large bowl. Lightly smooth the surface with a spoon or spatula.

8 Cover the containers with plastic wrap or a lid and refrigerate for at least 2 hours. The ideal is to leave it for between 3 and 4 hours so that the texture is perfect.

9 Just before serving, garnish with fresh berries, mint leaves and a little more lemon zest if you want an extra touch of aroma and color.
