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.

What each ingredient does
- Oranges
- Juice and peel supply the main flavour and aroma of the jelly.
- Isinglass or gelatine
- Sets the liquid into a firm, wobbly jelly as it cools.
- Sugar syrup
- Adds sweetness and body, helping the jelly hold its texture.
The step that matters
Remove the peels before the syrup becomes too bitter. Citrus peel releases bitter oils and pith compounds the longer it cooks in hot syrup, so over-boiling it makes the finished jelly taste bitter rather than fragrant.
