Instructions

1. Preheat the oven to 180C/160C Fan/Gas 4.

2. Use your hands to mulch the egg whites, sugar, coconut, lime zest and juice in a bowl until they lightly come together.

3. With wet hands, press the mixture into a flat, square shape about 1cm/0.5in high.

4. Use a small upturned liqueur glass to cut out small rounds, and place on a lightly oiled or nonstick baking tray.

5. Bake for 12-15 minutes in the centre of the oven until very lightly golden, just touched with colour.

6. Cool the macaroons on a wire rack, and store in an airtight jar.
