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 ↓

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Potatoes
- Provide the starchy base that becomes soft and creamy when boiled and mashed.
- Cream or butter
- Adds fat and richness, giving the potatoes a smooth, silky texture.
- Flour
- Lightly coats the potatoes, helping thicken the creamy mixture when dredged.
- Milk
- Adds moisture and softness when potatoes are mixed with it in the alternative method.
The step that matters
Drain the water and add cream or butter. Potatoes should be drained well before the fat is added, because excess water dilutes the cream or butter and makes the mash loose and watery.
Swap the potato
How well each one fits the dish's main ingredients (cream, pepper, flour, milk):
- Potatothe original
- Spinachfits about as well
- Arrowrootfits about as well
- Capsicumfits about as well
Fit is the average pairing score against cream, pepper, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
