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):
- Vanillafits better
- Orangefits better
- Raspberryfits better
- Applethe original
Fit is the average pairing score against lemon, sugar, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
