1 scant cup (4.4 oz) powdered sugar, (125 g)
2 1/3 cup (7 oz) ground almonds, (200 g)
Grated zest and juice of half a lemon
You'll also need a food processor and plastic wrap.
Cut a large piece of plastic wrap and place it on the work counter. Blitz the powdered sugar, ground almonds, egg, lemon zest and juice in a food processor. It’ll form itself into a dough ball.
