In a large bowl, mix all the dry ingredients. In a smaller bowl, mix the wet ingredients and jalapeños. (The vinegar with curdle the milk a little.) Add the wet ingredients to the dry mixture all at once. Stir until just blended.
Heat a large pot of oil to 375 degrees F. Drop the hushpuppy mix by the spoonful into the hot oil. Cook for about 4-5 minutes or until golden brown. Check the first few for doughiness. Repeat with the rest.
Scoop the hushpuppies out of the oil and place on paper towels. Salt if needed.
