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

What each ingredient does

Milk
Forms the liquid base of the custard that the yolks thicken.
Egg yolks
Thicken the custard as they heat, giving it a smooth, set texture.
Egg whites
Whipped into a stiff foam that forms the light floating topping.
Sugar
Sweetens the custard and helps balance the flavor.
Currant jelly
Adds sweetness and fruity flavor to the whipped topping.

The step that matters

Boil the custard only until it begins to thicken. Egg yolks set as they heat, but overheating makes them curdle and turn grainy. Stopping as soon as the custard begins to thicken keeps it smooth.

Swap the currant

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

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

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