How to make
Dissolve the yeast in a cup of warm milk. Sift the flour and along with the eggs, sugar, pinch of salt, lemon zest, butter and 2 cups of milk, knead a soft dough.
Leave it in a warm area to rise and double in volume, then roll it out into a sheet with a thickness of 3/4″ (2 cm) and using a glass, cut circles out.
Leave to rise again for half an hour. Preheat oil in a deep fryer or frying pan and fry the donuts evenly. Drain them on a grill with a paper towel underneath.
Serve them filled with cream, jam, a salty stuffing or sprinkled with powdered sugar.
