PREPARATION

Whisk egg whites until they form stiff peaks.

Gently fold in the ground hazelnuts and sugar. Fold only until the ingredients are incorporated.
Using a tablespoon, spoon lumps of the egg white mixture onto a baking tray lined with parchment paper.

Top each cookie with a hazelnut and gently press the hazelnut into the top of the cookie.
Cook for 10-12 minutes at 180°C/350°F.
