Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Heef Liver
Ingredients
Directions
Prepare
Wash the liver and cut it into ½-inch thick slices.
Roll the liver slices in powdered crackers.
Fry and serve
Heat butter and lard in a frying pan until smoking hot.
Fry the liver quickly, ensuring it doesn't burn, until browned on both sides.
Transfer the liver to a platter and cover it.
In the same pan, fry the sliced onions until browned and use them to garnish the liver.
Optionally, make gravy from beef drippings and pour it over the liver.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef liver
- Is the main protein, cooked quickly to stay tender with a browned crust.
- Powdered crackers
- Coat the slices, forming a crisp browned crust when fried.
- Butter
- Adds richness and flavour and helps the liver brown in the pan.
- Lard
- Provides a high-heat frying fat that browns the coating without burning quickly.
- Onion
- Frying until browned adds sweetness and savoury aroma as a garnish.
The step that matters
Fry the liver quickly. Liver is lean and dries out and toughens when overcooked. A hot pan and a short fry brown the coating while keeping the inside tender, so watch closely to prevent burning.
