2 1/2 cups all-purpose flour
1/3 cup sugar
6 tbsp (3/4 stick) unsalted butter
1/2 tsp baking powder
1 tsp mixed orange and lemon zest
2 large eggs
1/4 cup Marsala
Peanut or olive oil for frying, as needed
Confectioners' sugar, for dusting
1. In the bowl of a stand mixer fitted with the paddle attachment, mix the flour, sugar, butter, baking powder, and citrus zest. Blend in the eggs and Marsala. Mix until smooth, about 2 minutes.
2. Remove the dough from the bowl and shape into small balls about 1/2 ounce each and about 1/2 inch in diameter.
3. Heat the oil in a deep fryer or deep pot to 350 degrees F. Cook the castagnole, in batches, until they have a dark color, about 3 minutes.
4. Drain on paper towels. Dust with confectioners' sugar and serve warm.
