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 ↓

Ingredients
Directions
Prepare
Boil the Irish potatoes until tender, then mash them finely.
Season the mashed potatoes with butter, pepper, and coarse sea salt.
Shape and cook
Flour your hands and shape the potato mixture into small rolls.
Flatten each roll to about ¼ inch thick.
Fry the cakes in lard or bake them on a greased griddle until brown.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Irish potatoes
- Form the bulk of the cakes, providing starch that holds the shape once mashed and cooked.
- Butter
- Adds richness and moisture, and helps the cakes brown and taste savoury.
- Flour
- Dusted on the hands so the mixture does not stick while shaping the rolls.
The step that matters
Flatten each roll to about ¼ inch thick. Even thickness lets the cakes cook through at the same rate, so thin spots do not burn while thick centres stay raw.
Swap the potato
How well each one fits the dish's main ingredients (butter, pepper, flour):
- Shallotfits better
- Chivefits about as well
- Capsicumfits about as well
- Potatothe original
Fit is the average pairing score against butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
