The Hanukkah tradition of frying in oil is considered the culinary equivalent of lighting a menorah. A deep-fat thermometer is an essential tool for deep-frying; check that your oil returns to 375 degrees F between batches; this prevents the food from absorbing it.
2 apples (1 pound), peeled, halved lengthwise, cored, and sliced 1/4-inch thick
Confectioners' sugar, for dusting
Stir together flour, granulated sugar, and salt, then add beer, and whisk to combine. Heat oil in a 5-quart heavy pot until the thermometer registers 375 degrees F.
Dip apple slices in batter, shaking off excess, and fry, about 8 at a time, until golden, about 1 1/2 minutes on each side. Transfer fritters with a slotted spoon to paper towels to drain. Serve warm, dusted with confectioners' sugar.
