Ingredients
Method
Grease a 23cm x 32cm x 6cm deep, ovenproof dish (14-cup capacity).
Beat egg whites in a large bowl of an electric mixture until frothy. With the motor operating, gradually add sugar, 1 tblsp at a time, beating well after each addition until the sugar is dissolved. Continue to beat for a further 5 minutes, or until thick and glossy.
Beat in cornflour and vinegar until just combined. Spoon meringue into prepared dish. Smooth over top.
Cook in a very slow oven (120C) for about 55 minutes or until top is dry. Turn off oven. Cool in oven with door ajar for 30 minutes. Remove. Cool completely.
To make the topping, whip cream in the small bowl of an electric mixer until soft peaks form.
Spread cream over meringue, leaving a 2cm border. Sprinkle over raspberries and blueberries. Cover. Refrigerate for 4 hours, or overnight.
About 2 hours before serving, combine icing sugar, vanilla, and 1 tblsp water in a bowl. Stir in strawberries until coated. Refrigerate.
Just before serving, spoon strawberries and syrup overthe meringue. Scoop into bowls.
