Notes
The consistency of your batter is crucial for perfect hush puppies. If it’s too runny, your hush puppies will absorb too much oil and become greasy. If it’s too thick, they’ll be dense and doughy in the center. Aim for a consistency similar to thick Belgian waffle batter that holds its shape when scooped. Different brands of cornmeal may absorb liquid differently, so be prepared to adjust your milk quantity slightly if needed.
