Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold mashed potatoes
- Provide the bulk and starch that hold the cakes together and give a soft interior.
- Eggs
- Bind the potato mixture so the cakes keep their shape while frying.
- Flour
- Creates a dry coating that helps the outside brown and crisp in the fat.
- Butter or lard
- Conducts heat to the cakes and drives browning and a rich flavor on the surface.
The step that matters
Fry in hot fat. If the fat is not hot enough, the cakes absorb oil and turn greasy and pale before a crust forms. Hot fat sets the coating quickly and drives browning, so the cakes stay intact and golden.
Swap the potato
How well each one fits the dish's main ingredients (egg, flour, butter):
- Chivefits better
- Shallotfits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against egg, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
