Combine cornmeal (for best results, use 2 cups coarse cornmeal and 1 cup fine cornmeal or cornmeal flour), baking powder and salt in a large mixing bowl. Stir in eggs and enough milk to form a soft dough. Stir in onion.
Prepare your deep-fryer according to manufacturer’s directions. If deep-frying on a stove-top, use a cooking or candy thermometer and a deep sided pot large enough to hold enough oil to submerge the Hush Puppies. Heat oil to 375° F (190° C).
Drop batter by the tablespoonful into the hot oil. You can fry 8 to 10 of these at a time, but don’t crowd the pan. Remove when they are golden brown using a slotted spoon or strainer. Drain on a dish or tray covered with a paper towel.
