To Cook Frogs' Legs

Ingredients

Directions

Prepare

  1. If not pre-prepared, carefully strip the skin from the frogs' legs and wash them in cold water.

  2. Dry the legs well on a towel or napkin.

  3. Season with salt, pepper, and lemon juice.

Coat and fry

  1. Beat the egg and season it with salt and pepper.

  2. Dip the legs into the egg, then coat them with bread-crumbs.

  3. Plunge the legs into boiling fat and fry for 5 minutes.

  4. For best results, use a wire frying basket.

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

What each ingredient does

Frogs' legs
Provide the tender meat that is the main substance of the dish.
Egg
Binds the crumb coating so it adheres to the legs during frying.
Bread-crumbs or cracker-crumbs
Form a crisp, golden coating that browns in the hot fat.
Lemon juice
Adds acidity that brightens the mild flavour of the meat.

The step that matters

Drying the legs before coating. Surface moisture keeps the egg and crumbs from sticking evenly and can make hot fat spatter. Thoroughly dry legs give a crisper, more even crust when plunged into the boiling fat.
