Why it works: Sugar and red currant 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 ↓
Raspberry Jam Without Seeds
Ingredients
Directions
Prepare the fruit
Bruise the currants in a preserving pan with 1 pint of water.
Add the picked raspberries and stir over heat for a few minutes.
Rub the mixture through a cane sieve into a large pan.
Make the jam
Boil the sugar with just enough water to dissolve it until it reaches the pearl stage.
Add the pulp to the sugar and boil sharply for 20 minutes, stirring constantly.
When the jam drapes off the edge of the spoon, pour it into pots.

What each ingredient does
- Raspberries
- Provide the main fruit flavour and most of the jam's body once pulped.
- Red currants
- Add natural pectin and tartness to help the jam set.
- Sugar
- Sweetens the jam and, boiled and concentrated, helps it set and keeps it preserved.
The step that matters
Boiling the pulp with the sugar. Boiling sharply for the full 20 minutes concentrates the sugar and drives off water so the pectin can gel. Stirring constantly prevents the sugar from scorching on the base of the pan, which would give a burnt taste.
