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.

Sugar and milk barely smell alike, yet cooks put them together in 77,875 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

Eggs
Yolks add richness and body, while whipped whites add airy lightness to the custard.
Milk
Forms the liquid base that the custard sets from, providing moisture and creaminess.
Rennet wine
Contains rennet, an enzyme that coagulates the milk proteins so the custard sets.
Crushed sugar
Adds sweetness and helps stabilise the beaten yolks.

The step that matters

Gently fold in the whipped egg whites. Whipped whites hold air only while intact; vigorous stirring deflates them, leaving a denser custard with less lift.

Swap the peach

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

  1. Vanillafits better
  2. Figfits about as well
  3. Applefits about as well
  4. Peachthe original

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