Melt the butter, mix it with the sifted flour and sugar, then add the egg whites.
Spread the mixture onto a baking tray lined with baking paper, using a spoon to form even circles.
Bake at 180°C in a fan oven for approx. 8-10 minutes or until the edges begin to brown.
Using a spatula, turn the mixture upside down onto an upturned bowl and press lightly with your hands (beware of the heat!) to create the “nest” shape.
Mix the whipped cream with the custard to make the diplomat cream.
Fill the thuiles with the resulting cream, garnish with fresh fruit and finish with plenty of Fabbri Top Caramel.
