Tips
Once the apple fritters are fried, put them on paper towels to remove all excess oil; when frying them, make sure they are well separated to prevent them from sticking. Also, sprinkle sugar over them while they are still hot, and if you want to give them an extra twist, add some powdered spice such as cinnamon.
