Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Liver Croquettes
Ingredients
Directions
Prepare the liver
Boil the liver in enough water to cover it.
Once cooled, mash the liver finely with a large spoon.
Make the mixture
Mix in the boiled potato or cold rice.
Add the egg, cracker crumbs, salt, pepper, and cayenne pepper.
Incorporate a little of the stock.
Form the mixture into croquettes.
Coat and fry
Roll each croquette in egg, then in cracker crumbs.
Fry in hot lard until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver
- Forms the main body and rich flavor of the croquettes.
- Boiled potato or cold rice
- Adds starch and bulk that help the mixture hold together and stay moist.
- Egg
- Binds the mixture and forms a set coating for browning.
- Cracker crumbs
- Absorb moisture and add a crisp, browned outer layer.
- Stock
- Adds moisture so the mixture is easier to shape and stays tender.
The step that matters
Mashing the liver finely. Fine mashing gives an even, smooth texture; coarse pieces make the croquettes crumble when shaped and fried. Binding with egg and starch helps them hold their shape in hot fat.
Swap the potato
