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

What each ingredient does

Powdered alum
Causes the milk proteins to clump and separate from the liquid, which is what turns the milk.
Milk
Provides the liquid base and the proteins that clump and separate when alum is added.

The step that matters

Adding the alum to boiling milk. The alum needs to mix evenly into the hot milk so the proteins clump uniformly. Uneven mixing leaves pockets of uncoagulated milk and uneven separation.

Swap the nutmeg

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

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

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