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

What each ingredient does

Milk
Forms the body of the custard, providing liquid and richness once thickened.
Egg yolks
Thicken the custard as they cook, giving it a smooth, creamy structure.
Egg whites
Whip into stiff foam that holds the floating meringue's airy structure.
Sugar
Sweetens the custard and meringue and helps stabilise the whipped whites.

The step that matters

Cooking the custard over the double boiler. Egg yolks thicken gently at moderate heat, but overheating causes them to scramble and curdle. Stirring constantly and keeping the water below a hard boil gives a smooth, creamy result.

Swap the red currant

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