The flavor team

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.

Sugar and currant barely smell alike, yet cooks put them together in 12,256 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Isinglass
Gelatine-like protein that sets the juice into a firm, wobbly jelly when cooled.
Small fruit
Supplies the juice and the flavour of the jelly.
Best loaf sugar
Sweetens the jelly and helps give it body as the syrup thickens.

The step that matters

Skim the syrup until clear. Skimming removes foam and impurities from the boiling sugar, so the finished jelly is clear rather than cloudy.
