Clip off the heads and stalks with scissors.
Cook the fruit

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black currants
- Provides the main fruit flavour and body, with natural pectin that helps the preserve set.
- Red currant juice
- Adds extra fruit flavour and acidity, which brightens the sweetness and supports setting.
- Loaf sugar
- Sweetens and preserves the fruit by drawing out water, and helps the preserve thicken and set.
The step that matters
Carefully remove the fruit from the sides of the pan. Fruit left stuck to the hot sides can scorch as the mixture thickens, and the burnt bits can spread a bitter, smoky taste through the whole batch.
Swap the red currant
How well each one fits the dish's main ingredients (black currant, sugar):
- Vanillafits better
- Red currantthe original
- Blueberryfits less well
- Raspberryfits less well
Fit is the average pairing score against black currant, sugar. Candidates are from the same food group and used in at least 100 recipes.
