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

Buttermilk
Heating it separates the curds from the thin whey, which is the drink being made.
Sugar
Adds sweetness to the finished whey, adjusted to taste.

The step that matters

Pour off the whey. Heating the buttermilk causes the proteins to clump into curds, leaving a thin, clear liquid. Pouring off only the whey keeps the curds out, so the drink stays smooth rather than grainy.

Swap the nutmeg

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

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Gingerfits about as well
  4. Dillfits about as well

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