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.

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

What each ingredient does

Egg yolks
Thicken the custard as they set when gently heated, giving it a rich, smooth body.
Lemon rinds
Add fragrant oils and bright, aromatic lemon flavour.
Sugar
Adds sweetness and balances the acidity of the lemon.
Rich wine
Adds depth and body to the flavour of the custard.
Brandy
Adds aromatic warmth and a boozy depth of flavour.

The step that matters

Stir the mixture over heat until it thickens. Egg yolks thicken as their proteins coagulate with heat, but if the custard gets too hot it can curdle or scramble. Stir constantly and remove from heat as soon as it coats a spoon.

Swap the lemon

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

  1. Vanillafits better
  2. Apricotfits better
  3. Applefits better
  4. Lemonthe original

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