Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starch that forms the bulk and soft, fluffy texture of the mash.
- Butter
- Adds fat and richness, coating the potatoes for a smooth, silky mouthfeel.
- Cream
- Adds moisture and fat, loosening the mash and making it smoother and creamier.
The step that matters
Drain and dry the potatoes. Excess water dilutes the mash and makes it watery. Drying the cooked potatoes lets them absorb the butter and cream and keeps the texture light.
Swap the potato
How well each one fits the dish's main ingredients (butter, cream, pepper, sugar):
- Capsicumfits about as well
- Potatothe original
- Leekfits about as well
- Spinachfits less well
Fit is the average pairing score against butter, cream, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
