Café Du Monde, the original French Market café in New Orleans, sells dry beignet mix on its retail website, Shop.CafeDuMonde.com. A 2-pound bag retails for approximately $4 as of 2015.
To prepare Café Du Monde beignets using its packaged dry mix, combine 2 cups of dry mix with 7 ounces of water. Use a spoon to mix only until the ingredients are thoroughly incorporated. Adjust the ingredients to achieve the desired consistency, which should be smooth and resemble that of drop biscuits.
Transfer the dough onto a floured surface. Sprinkle flour onto the dough, roll the dough out flat, and use a pizza cutter to cut it into two-inch squares. Do not re-roll and re-cut the inevitable dough scraps, as doing so develops the gluten, which yields tougher beignets. Instead, fry the beignet scraps as they are.
Frying the beignets in cottonseed oil is preferable, although it's also possible to use vegetable oil. The oil should be heated to 370 degrees Fahrenheit. For best results, fry the beignets in small batches. Large batches or an overcrowded frying pan potentially reduce the temperature of the oil, which results in flat beignets. The beignets are done when they turn light golden brown and puff up.
