Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sweet potatoes
Provide the starchy body and bulk that the whole dish is built on.
Butter
Adds fat and richness, giving the mash a smooth, silky mouthfeel.
Hot milk
Adds moisture and loosens the mash, helping it become light and fluffy when beaten.

The step that matters

Moisten with hot milk and beat until very light. Adding cold milk chills the starch and makes the mash stiff and dense. Hot liquid keeps it loose and smooth, and beating incorporates air for a lighter texture.

Swap the sweet potato

How well each one fits the dish's main ingredients (butter, pepper, milk):

  1. Potatofits better
  2. Capsicumfits better
  3. Tomatofits better
  4. Sweet potatothe original

Fit is the average pairing score against butter, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
