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):

  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.
