Knead the flour, butter, egg yolk, water, salt and 50 g sugar to form a dough. Let it rest for 1 hour in the refrigerator. Then roll out and cut out 48 circles. Put a Toffifee in the middle.
Beat the egg white and lemon juice until stiff while slowly pouring in the sugar. Sprinkle the egg whites on the circles until the toffifees are completely covered.
Bake at 175 ° for 15-20 minutes in a preheated oven.
