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

What each ingredient does

Oatmeal
Provides the starch and body that thicken the gruel as it cooks and gives it its main flavour.
Cold water
Extracts starch and flavour from the oatmeal during steeping and forms the liquid base of the gruel.

The step that matters

Boil for 10 minutes, stirring constantly. Oat starch can settle and scorch on the bottom of the pan. Constant stirring keeps the mixture even and lets the starch gelatinise smoothly as it thickens.

Swap the walnut

The recipe marks walnut as optional. How well each one fits the dish's main ingredients (cream, sugar, butter):

  1. Almondfits better
  2. Filbertfits better
  3. Pistachiofits better
  4. Walnutthe original

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