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

What each ingredient does

Milk
Forms the base of the drink and separates into curds and whey when heated with acid.
Lemon juice
Acid that curdles the milk, separating the solids from the clear whey.

The step that matters

Keeping seeds out of the milk. Lemon seeds can fall into the hot milk and are hard to remove once it curdles. Squeezing over a separate dish or sieve keeps the whey clean.

Swap the lemon

How well each one fits the dish's main ingredients (milk, sugar):

  1. Vanillafits better
  2. Figfits better
  3. Peachfits better
  4. Lemonthe original

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