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

What each ingredient does

Eggs
Bind the mixture and help it thicken as it cooks.
White sugar
Sweetens the marmalade and helps it set into a thick spread.
Apples
Add body and natural pectin to help the marmalade set.
Lemons
Provide acidity and aroma from the juice and rind.
Butter
Adds richness and a smooth, silky texture.

The step that matters

Boil the mixture for 10 minutes. Eggs can scramble or curdle if overheated, so the mixture needs steady heat and constant stirring. Boiling long enough lets the sugar and fruit thicken it into a spreadable set.

Swap the apple

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

  1. Vanillafits better
