Recipe by Bron from the Thermomix Forum
300g frozen Strawberries
150g icing sugar
2 egg whites and 2 teaspoons lemon juice
Blitz sugar to make icing sugar, then add strawberries and blitz on 6 for 30 seconds. Scrape down, place butterfly on blades, add egg whites and juice all in together! Program approx 2 mins speed 3 and 1/2! Delicious strawberry foam! Wow! Can be frozen, or apparently can keep in fridge for a while too.
Can be made with other frozen fruit, like pineapple, peach, banana and mango.
