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

What each ingredient does

Young sprouts or greens
Form the bulk of the dish, giving it its main body and cabbage flavour.
Butter
Adds fat and richness, making the mashed greens smooth and savoury.
Cream or milk
Adds moisture and softness, so the mashed greens hold together smoothly.

The step that matters

Press the boiled greens dry. Excess water left in the boiled greens makes the mash loose and soggy, so it will not hold a shape or dry enough to mold when heated.

Swap the onion

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

  1. Potatofits better
  2. Spinachfits about as well
  3. Capsicumfits about as well
  4. Onionthe original

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