The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: ethyl caproate (fruity, apple peel).

    Shared aroma: phenylacetaldehyde (hawthorne, honey).

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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

Milk
Forms the liquid base that thickens into the custard.
Egg whites
Beaten to stiff foam, they create the light, airy floating topping.
Sugar
Adds sweetness and balances the flavor of the custard.
Flour
Its starch thickens the custard and helps it hold its body.

The step that matters

Cook the mixture until well thickened. Flour starch and egg yolks thicken the custard as it heats. Too little cooking leaves it thin, while overheating can curdle the eggs and make the custard grainy.

Swap the vanilla

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

  1. Vanillathe original
  2. Raisinfits about as well
  3. Figfits less well
  4. Blueberryfits less well

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