This is the breading recipe my mom always used:
1 cup flour
1/2 tsp salt
1 slightly beaten egg
1 cup milk
1 Tbsp vegetable oil
1 medium eggplant, peeled and sliced into rounds or cut like fries
Add salt to flour, stir in egg and oil and gradualy add milk. I tend to only use 3/4 cup of milk. I think using the whole cup makes the batter too runny. Dip eggplant in batter and fry in hot oil. I have also adapted the recipe for my own family by adding other seasoning into the flour - Mrs. Dash or a combination of seasonings that I'm in the mood for! I also lightly salt the eggplant when it's done frying.
