Ingredients
2 cups cornmeal
2 tablespoons all-purpose flour
1 teaspoon baking soda
1 teaspoon baking powder
1 teaspoon coarse salt
1/2 cup grated onion
1/4 cup sliced green onion
1 large egg yolk
1 cup buttermilk
6 large egg whites
Canola oil, for frying
Preparation
In a large bowl, whisk together cornmeal, flour, baking soda, baking powder, and salt. Stir in onions. Combine egg yolk and buttermilk; stir into cornmeal mixture until combined.
In the bowl of an electric mixer fitted with the paddle attachment, beat egg whites until stiff. Gently fold into cornmeal mixture.
Fill a large deep skillet with 2 to 3 inches oil. Heat oil until it reaches 375 degrees on a deep-fry thermometer. Working in batches, drop batter, 1 teaspoon at a time, into the oil and cook, turning once, until the hush puppies rise to the surface and are golden brown, 2 to 3 minutes. Transfer to a paper-towel-lined plate. Serve immediately.
