Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Frog legs
Serve as the main protein; their mild, tender meat is the centre of the dish.
Sweet milk
Moistens the frog legs so the seasoned flour coating adheres evenly.
Seasoned flour
Forms a coating that browns and crisps in the hot fat.
Sweet butter or drippings
Frying fat that conducts heat, browns the coating, and adds rich flavour.

The step that matters

Fry slowly until crisp. Frying slowly over moderate heat lets the coating dry and brown evenly while the meat cooks through. Too much heat can scorch the flour before the inside is done, and too little leaves the coating greasy and soft.
