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 gives mashed potatoes their bulk and body.
- Hot cream
- Adds richness and fat, producing a smoother, silkier texture.
- Cold buttermilk
- Adds moisture and a slight tang, giving a lighter texture than cream.
- Butter
- Adds fat and flavour, enriching the mash and helping it feel smooth.
The step that matters
Mash the potatoes until fine. Potato starch ruptures as cells break down; overworking or using a gummy mash can make potatoes sticky or gluey, so mash gently until just smooth and add liquids warm or hot to keep the texture fluffy.
Swap the potato
How well each one fits the dish's main ingredients (cream, buttermilk, butter):
- Chivefits about as well
- Potatothe original
- Onionfits less well
- Horseradishfits less well
Fit is the average pairing score against cream, buttermilk, butter. Candidates are from the same food group and used in at least 100 recipes.
