- 3/4 cup milk or water
- 5 tablespoons unsalted butter, cut into small pieces
- 1/2 teaspoon salt
- Finely grated zest of 1/2 lemon
- 1 cup Italian “00” flour or 1 cup all-purpose flour
- 3 large eggs
- 6 cups vegetable oil for deep-frying
- 1/2 cup sugar
- 1 tablespoon cinnamon
- Special equipment: a deep-fat thermometer
- Bring milk, butter, salt, and zest to a boil in a 2-quart heavy saucepan over high heat, stirring just until butter is melted, then reduce heat to moderate. Add flour all at once, stirring vigorously with a wooden spoon until mixture is smooth and pulls away from side of pan, 1 to 2 minutes. Remove from heat and cool slightly, 1 to 2 minutes. Add eggs 1 at a time, stirring vigorously after each addition until smooth.
- Heat 2 inches of oil in a 4-quart deep heavy pot (preferably a cast-iron Dutch oven) over moderately high heat until thermometer registers 360°F.
- Sift together sugar and cinnamon into a bowl.
- While oil is heating, roll rounded tablespoons of dough into balls with dampened hands and put them on an oiled sheet of plastic wrap. Pick up a ball and make a hole in the middle with your thumb, then insert the handle of a wooden spoon in the hole. When oil reaches 360°F, carefully lower dough on handle into oil, then gently widen hole with a circular motion of spoon until dough rises to surface, about 30 seconds (don't worry if some break open). Remove spoon, leaving buñuelo cooking in oil, and repeat with 4 more balls. Fry, turning occasionally, until deep golden and cooked through, 6 to 7 minutes. Drain briefly on paper towels. Turn warm buñuelos in sugar mixture to coat.
- Form and fry more buñuelos, in batches of 5, in same manner.
