Most store-bought pancake mixes use flour, sugar, baking soda, and salt as part of the base. This is essentially the same set of ingredients you would use if you were to make the batter for your apple fritters from scratch. So all you need to do is get your oil hot enough to fry, add water to the pancake mix to bring it to the right consistency, whisk in a beaten egg, mix in your chopped apples, and start frying your fritters.
Among a plethora of different types of apples, using the right varieties is crucial for the very best flavor and texture. Tasting Table chatted with cookbook author Mark Filippelli to get his must-know tips for the tastiest apple fritters and he strongly recommended avoiding overly ripe apples as well as varieties such as Red Delicious or Fuji as their tender texture will not stand up to the cooking process.
