Sugar and nutmeg barely smell alike, yet cooks put them together in 23,364 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Oatmeal
Its starch thickens the water as it cooks, giving the gruel its body.
Thin cream
Adds fat for richness and a smoother, softer mouthfeel.
Sugar
Adds sweetness, adjusted to taste.

The step that matters

Cooking the oatmeal slowly in a double boiler. Oat starch needs a long, gentle cook to swell and soften fully. The double boiler holds the heat moderate, so the mixture thickens evenly and is less likely to scorch on the bottom of the pan.

Swap the nutmeg

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

  1. Nutmegthe original
  2. Cinnamonfits about as well
  3. Gingerfits less well
  4. Peppermintfits less well

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