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).

  2. Gelatin + creamtop 7% of all pairs

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

What each ingredient does

Eggs
Thicken the custard as they cook and give it a rich, set structure.
Gelatin
Sets the liquid custard into a firm, sliceable jelly when chilled.
Milk
Forms the liquid base of the custard and adds creaminess.
Sugar
Sweetens the custard and balances the tartness of the lemon.
Sherry
Adds aroma and a wine flavor that complements the custard.

The step that matters

Slowly pour the gelatin mixture into the custard while stirring continuously. Adding warm gelatin all at once or without stirring can cause uneven setting and lumps. Gradual addition with constant stirring distributes the gelatin evenly so the jelly sets uniformly.

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.
