This recipe for hush puppies is from "Southern Country Cooking from the Loveless Cafe," by Jane and Michael Stern. Serve this and a side of sour slaw with braised pork chops for a delicious meal.
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.
