Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Barberry Jelly
Ingredients
Directions
Prepare the fruit
Boil 1 quart of water in a stewpan.
Add the barberries to the boiling water, cover, and let them cool down.
Make the syrup
In another pot, heat 1 cup of clarified sugar with a little water until it boils, skimming off any foam.
Add the barberries to the boiling sugar mixture and let it simmer gently for 30 minutes or more.
Finish the jelly
Squeeze the juice of 3 lemons through a silk sieve into a basin.
Strain the barberry mixture into the lemon juice, then add the isinglass and mix well.
Reserve some barberries for garnish when serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barberries
- Provide the main fruit flavour and tartness, and the pectin-rich body of the jelly.
- Clarified sugar
- Adds sweetness and helps the jelly hold its set and clear appearance.
- Lemon juice
- Adds acidity that brightens flavour and supports setting.
- Isinglass
- Acts as the gelling agent that sets the liquid into a firm jelly.
The step that matters
Mixing in the isinglass. Isinglass is a gelatin-like setting agent. It needs to be fully dissolved and evenly mixed into the warm liquid, or the jelly may set unevenly.
