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

What each ingredient does

Milk
Forms the liquid base of the custard.
Sugar
Adds sweetness and balances the lemon's acidity.
Cornstarch
Thickens the milk as it boils, setting the custard.
Lemon rind
Adds bright lemon aroma from the oils in the zest.

The step that matters

Boil for 5 minutes, stirring constantly. Cornstarch must reach a boil to fully swell and thicken the liquid. Constant stirring prevents scorching on the pan bottom and stops lumps from forming.

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.
