Tropical Cookie and Fruit Stack
Beat together the flour, sugar and egg whites until smooth, then beat in the melted butter. Refrigerate for 30 minutes.
Preheat the oven to 180?C (160? fan), 350F, gas 4 and oil two large baking trays.
Spoon teaspoonfuls of the mixture onto the first baking tray and spread out with the back of the spoon to make 8 cm circles.
Bake for 8-10 minutes then repeat with the second tray. You need to make 18 biscuits in total.
Leave the biscuits to cool and crisp up on the tray then transfer to a wire rack.
Reserve a few tablespoons of the syrup and drain the rest then finely chop the pineapple chunks.
Layer the tuiles with the pineapple, drizzling over a little syrup as you go and sprinkle the final tuile with desiccated coconut.
