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).

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

What each ingredient does

Eggs
Set the custard as they thicken and add richness when cooked gently.
Gelatin
Sets the liquid custard into a firm jelly when chilled.
Milk
Forms the liquid base of the custard and adds creaminess.
Sugar
Sweetens the custard and balances the lemon and sherry.
Sherry
Adds aroma and flavour that complements the custard.

The step that matters

Stir the gelatin mixture into the custard. Adding the gelatin while stirring continuously keeps it evenly distributed. If it is added to a hot or lumpy custard without stirring, it can clump or set unevenly, so the jelly will not be smooth.

Swap the lemon

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

  1. Strawberryfits better
  2. Figfits better
  3. Pineapplefits better
  4. Lemonthe original

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