Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the dish, with starch that gives the mash its body once cooked and mashed.
- Butter
- Adds fat and richness, coating the starch for a smoother, silkier texture.
- Cream or hot milk
- Adds moisture and softness, loosening the mash and making it creamy.
The step that matters
Beat the potatoes for five minutes until fluffy. Beating works the potato starch and releases it, which makes the mash light and fluffy. Overworking a warm mash over time can turn it gluey, so stop once it is fluffy.
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.
