Why it works: Pepper and tomato are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fried Liver
Ingredients
Directions
Prepare the liver
Cut the liver into thick slices, wash, and dry them.
Dust the liver slices with flour and season with salt and pepper.
Fry and serve
Heat the beef dripping in a frying pan over medium heat.
Cook the liver gently, turning constantly until done.
Place the cooked liver on a hot dish with fried tomatoes.
In the same pan, stir flour into the remaining dripping until smooth.
Gradually add the brown stock and tomato catsup, stirring well.
Let the sauce boil, season with pepper, cayenne, and salt, then strain it into the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calves' liver
- Forms the main body of the dish, cooked gently to stay tender.
- Flour
- Dusting helps the liver brown, and it thickens the sauce when stirred into the dripping.
- Beef dripping
- Fat for frying that gives the liver browning and rich flavour.
- Brown stock
- Liquid that turns the flour and dripping into a savoury sauce.
- Tomato catsup
- Adds sweetness and acidity to the brown sauce.
The step that matters
Cook the liver gently, turning constantly until done. Liver turns dry and grainy when overcooked, and constant turning helps it cook evenly and brown without toughening. Stop once it is just cooked through.
