The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oranges
- Provide the bitter peel and pulp that give marmalade its characteristic flavor and body.
- Lemon
- Adds acidity that brightens the flavor and helps the marmalade set.
- Water
- Softens the sliced peel and extracts its pectin and flavor during the long simmer.
The step that matters
Adding the lemon juice near the end. Acid added too early can slow softening of the peel, while adding it when nearly cooked helps the pectin gel properly and brightens flavor. Check the set before stopping the cook.
