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

What each ingredient does

Black currants
Provide the fruit base, along with their natural pectin and acidity that help the jam set.
Sugar
Sweetens the jam and helps it thicken and keep as the mixture reduces.

The step that matters

Skimming the foam while boiling. Foam rises as the fruit boils and contains impurities that can cloud the jam and affect its flavour. Skimming it off keeps the jam clear and clean-tasting.

Swap the red currant

How well each one fits the dish's main ingredients (black currant, sugar):

  1. Vanillafits better
  2. Red currantthe original
  3. Blueberryfits less well
  4. 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.
