Step 1

Preheat oven to 180C. Line four baking trays with non-stick baking paper.

Step 2

To make the sorbet, place the mango, lime rind and lime juice in the bowl of a food processor and process until almost smooth. Press firmly into a metal container, cover with foil and place in the freezer for 25 minutes or until firm.

Step 3

Meanwhile, use an electric beater to whisk egg white in a clean, dry bowl until soft peaks form. Gradually add sugar and whisk until dissolved. Stir in flour, butter and extra lime rind.

Step 4

Spoon 4 teaspoonfuls of mixture onto each of the prepared trays and spread into 7cm-diameter discs. Bake half the wafers in oven, swapping trays halfway through cooking, for 5 minutes or until golden. Repeat with the remaining wafers.

Step 5

Spoon the sorbet into serving bowls and serve with wafers.
