Ingredients

• 4 egg whites
• 1/8 teaspoon white vinegar
• 240g caster sugar
• finely grated zest of 1 green [unripe] lemon
• 100g walnuts, chopped into small pieces
• cocoa, for dusting

Method

• Preheat the oven to 100°C, and line a baking tray with baking paper.
• Beat the egg whites until frothy in a KitchenAid or Kenwood mixer or with a hand-held mixer on medium speed. Add the vinegar, increase the speed a little and gradually add the sugar, in about 4 additions. Continue beating until stiff peaks are formed.
• Fold in the zest and walnuts using a metal spoon.
• Use two dessertspoons to drop rough mounds onto the prepared baking tray. Bake for 1 hour then reduce the temperature to 70°C and bake until dry [about 30 minutes–1 hour].
• Allow to cool then store in an airtight container.
• Dust lightly with cocoa before serving.
