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

What each ingredient does

Turnips
Form the main body of the dish, mashed into a smooth, soft texture.
Butter
Adds richness and a smoother, silkier mouthfeel to the mashed turnips.
Flour
Thickens the mashed turnips slightly, giving them a firmer body.

The step that matters

Drain the turnips thoroughly. Excess water left after boiling dilutes the flavour and loosens the mash, so it turns watery rather than smooth. Draining well keeps the texture thick and concentrated before the butter and flour are added.

Swap the turnip

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

  1. Shallotfits better
  2. Chivefits about as well
  3. Capsicumfits about as well
  4. Turnipthe original

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