Sift together the sugar, flour, baking powder and cloves. Make a well in the sugar mixture and pour the eggs into the well. Work the eggs into the mixture, first with a fork, then with your hands, until you have a smooth dough.
Line a baking tray with foil. Roll dough into 3cm balls and place on the prepared baking tray 5cm apart. Flatten each biscuit with the bottom of a glass. Cover with a clean dish towel and let rest overnight. Biscuits will spread.
Preheat an oven to 180 degrees C.
Bake in the preheated oven until golden, about 15 minutes. Remove biscuits from pan immediately as they come out of the oven or they will stick. Cool completely on a wire rack.
