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 ↓

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: 2-nonenal (fatty, green).
Egg and pepper barely smell alike, yet cooks put them together in 50,580 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Form the body of the croquettes, giving them their soft, moist interior.
- Egg whites
- Bind the potato mixture so the balls hold their shape.
- Egg yolks
- Act as a glue so the cracker crumbs stick to the outside.
- Cracker crumbs
- Form a crisp coating that browns during frying.
The step that matters
Frying in hot lard until golden brown. If the lard is not hot enough, the coating absorbs fat and turns greasy instead of crisp. Too hot, and the outside browns before the potato inside heats through.
Swap the potato
How well each one fits the dish's main ingredients (egg, pepper):
- Capsicumfits better
- Spinachfits better
- Asparagusfits better
- Potatothe original
Fit is the average pairing score against egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
