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 cook gently and set it into a smooth, creamy texture.
Sugar
Sweetens the custard and dissolves fully into the warm juice before the eggs are added.
Clear currant juice
Provides the main flavour and tartness of the custard.
Lemon juice
Adds acidity that brightens the sweetness and balances the fruit flavour.

The step that matters

Cook the custard gently in boiling water. Egg yolks thicken through gentle heat; if the custard cooks too fast or too hot, the yolks can scramble and turn grainy. Gradually mixing the warm juice into the yolks first helps prevent curdling.

Swap the currant

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

  1. Orangefits better
  2. Pearfits better
  3. Vanillafits better
  4. Currantthe original

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