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

What each ingredient does

Salt cod
Salt-cured fish that provides the main body and flakes once soaked and cooked.
Parsnips
Give the dish its natural sweetness and a soft, mashable texture when cooked.
Butter
Adds fat and richness, giving the mashed parsnips a smooth, savoury flavour.
Cream or milk
Adds moisture and creaminess, loosening the mash into a smooth texture.

The step that matters

Soak the salt cod overnight. Salt cod is heavily salted, and soaking in water draws out much of that salt. Skipping or shortening the soak leaves the fish harshly salty.

Swap the parsnip

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

  1. Asparagusfits better
  2. Chivefits better
  3. Potatofits better
  4. Parsnipthe original

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