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.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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

Egg white
Whipped into the warm mixture to give the island a light, airy texture.
Cornstarch
Thickens the liquids as it heats, giving the island and custard their body.
Milk
Forms the base of the custard, providing creaminess and body.
Sugar
Adds sweetness and helps set the island's texture.
Whipped cream
Adds richness and a soft, cool topping that contrasts the warm custard.

The step that matters

Stirring in the beaten egg white while the mixture is warm. The mixture should be warm but not hot when the egg white goes in, so the egg white stays light and foamy rather than scrambling or deflating. Stirring gently keeps the air trapped in the beaten white, giving the island its light texture.

Swap the lemon

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

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

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