Use a springform cake tin in any size from 20 cm to 26 cm. Draw circles the size of your cake tin onto baking paper. Spray the paper and put onto a flat baking tray. You will need 2 to 3 trays.
Beat egg whites until frothy and aerated with a couple of drops of lemon juice.
Slowly add the sugar beating between each addition until the mixture is thick and glossy and the sugar is dissolved.
Fold through hazelnut meal. Put the mixture into a piping bag and pipe rounds onto the parchment paper. Alternatively spread into circles with a palet knife approximatly 5 cm thick.
Bake the circles in a 150 deg oven for approximately 30- 40 min, or until golden and firm. Cool before carefully removing the paper.
Ideally you will have three circles, however two will work just as well.
