Why it works: Red currant and sugar are a kitchen classic. They rank in the top 26% of all ingredient pairs, and cooks put them together in 1,156 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Wild Rasp and Red Currant Jelly
Ingredients
Directions
Extract the juice
Clean the fruit and place it in a preserving pan with 2 quarts of water.
Boil over medium heat for one hour, stirring and bruising the fruit constantly.
Turn the mixture into a jelly bag and let it strain overnight.
Make the jelly
The next day, pour the fruit juice back into the pan and boil briskly for half an hour to evaporate the water.
Add 7 lbs of lump sugar and boil quickly for 2 minutes, or more slowly for half an hour.

What each ingredient does
- Red currants
- Their natural pectin and acidity help the juice set into a firm jelly.
- Wild raspberries
- They supply the main flavour and colour, and their juice gives the jelly body.
- Lump sugar
- Sugar binds water and helps the pectin gel, while also sweetening the jelly and preserving it.
The step that matters
Boiling down after adding the sugar. Sugar must dissolve fully and the jelly must reach a rolling boil so the pectin and acid can set it. Boiling too briefly leaves it runny, while boiling too long can darken the colour and dull the flavour.
