Mix together the eggs and sugar. Add the ricotta, milk, orange extract and lemon zest. Add the flour, baking powder and salt to the egg mixture. Beat just until smooth.

Fill a deep fryer pan with oil, at least 3 inches deep. Heat oil and drop dough with a teaspoon into the hot oil. Fry until golden brown, about 2 minutes on each side. Remove from the oil and drain on a plate covered with paper towels.

Let cool for 5-10 minutes before dusting with powdered sugar and serve.
