Mixed Berry Mousse

In a pan of simmering water, add the mixture of frozen berries and half the amount of sugar. Cook the berries until they feel soft.

When the berries are soft, turn off the heat. Drain, keeping the juice. With the drained berries, using a processor, pulse the berries into a thick mixture, pour into a bowl and leave to cool

Separate the eggs. Using the egg whites only and the 1/2 - 1 tbsp of fresh lemon juice (depending on your own taste), in a clean food processor whisk until soft peaks form. At this stage add the last of the sugar. Whisk until firm peaks form - when the whisk leaves deep markings in the white mixture.

Add 1 spoonful of the egg white to the mixed berries. stir the egg white in quickly until all combined.

Now gradually fold the rest of the whites into the berry mixture. Do this slowly and carefully. Doing this too quickly will knock out all the air from the whites. Do not combine all the mixture, leave some of the whites still showing.

To serve, spoon the mixture into 4 tall glasses. Leave to set for 2-3 hours in the fridge. You can leave them to set over night. Once set drizzle the kept berry juice over the mousse, and top with fresh berries. The berry juice is also ideal for making smoothies, Jelly, and ice cream with :) enjoy.
