Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Directions
Make the mixture
In a saucepan, bring the milk or cream to a boil.

Boil for 5 minutes, stirring constantly.

Once cool, shape into cone-shaped balls, coat 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
- Eggs
- Bind the mixture and help it set as it boils.
- Mashed potatoes
- Add body and moisture, helping the mixture hold its shape.
- Milk or cream
- Adds moisture and richness to the mixture, softening the meat and potato.
- Butter
- Adds fat and richness, contributing flavour and a tender texture.
- Cracker crumbs
- Form a dry outer coating that browns when fried.
The step that matters
Cool the mixture completely before shaping. A warm mixture is soft and sticky, so the croquettes lose their shape and can burst or crack in hot fat. Chilling firms the starches and egg proteins so the balls hold together while frying.
Swap the parsley
