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

What each ingredient does

Corn starch
Thickens the milk as it heats, giving the custard its body.
Eggs
Add richness and help set the custard as it thickens.
Milk
Forms the liquid base of the custard.
Powdered sugar
Sweetens the custard and dissolves easily into the milk mixture.

The step that matters

Stir briskly and let it boil up once or twice until thickened. Starch must reach a boil to fully swell and thicken, but stirring keeps it from scorching on the bottom of the pan. The eggs can curdle if overheated, so the custard should only boil briefly.

Swap the lemon

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

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

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