Why it works: Beef and pepper are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,971 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fried Beef Liver
Ingredients
Directions
Prepare
Cut the beef liver into thin slices, about ¼ inch thick.
Pour boiling water over the slices to seal the pores and juices.
Coat and fry
Roll the slices in flour or bread crumbs, and season with salt and pepper.
Dip the coated slices in beaten egg.
Fry in hot fat mixed with ⅓ cup butter until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef liver
- Forms the main body of the dish, cooking to a tender interior under a crisp coating.
- Flour or bread crumbs
- Forms a dry coating that browns in the hot fat and gives a crisp outer layer.
- Egg
- Binds the coating to the liver so it stays attached during frying.
- Butter
- Adds fat for frying, contributing browning and a rich flavor.
The step that matters
Frying in hot fat until golden brown. The fat must be hot enough to brown the coating quickly. If it is too cool, the coating absorbs excess fat and turns greasy, while the liver can overcook before the crust forms.
