Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starch and body that make up the mash.
- Butter
- Adds fat for richness and a smooth, silky mouthfeel.
- Cream
- Adds moisture and fat, loosening the mash and softening its texture.
The step that matters
Let the potatoes sit on the stove until completely dry. Surface water left on the potatoes dilutes the butter and cream, making the mash soggy and loose. Drying lets excess moisture evaporate so the mash holds together and absorbs added dairy well.
Swap the potato
How well each one fits the dish's main ingredients (butter, cream):
- Potatothe original
- Onionfits about as well
- Leekfits less well
- Chivefits less well
Fit is the average pairing score against butter, cream. Candidates are from the same food group and used in at least 100 recipes.
