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

What each ingredient does

Cherries
Provides the main fruit body and sweet-tart flavour of the preserve.
Raspberries
Adds aroma and bright fruity flavour to the preserve.
Red currants
Their natural pectin helps the preserve thicken and set.
White currants
Their natural pectin helps the preserve thicken and set, and add tart acidity.
Granulated sugar
Adds sweetness and, at this concentration, helps the preserve set and keep.

The step that matters

Stirring the sugar in while boiling. Sugar is added to a hot, thick fruit mixture that can scorch on the bottom of the pot. Constant stirring spreads the heat and prevents burning, which would give the preserve a bitter, caramelised taste.

Swap the white currant

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

  1. Raspberryfits better
  2. Vanillafits better
  3. Blueberryfits better
  4. White currantthe original

Fit is the average pairing score against red currant, sugar. Candidates are from the same food group and used in at least 100 recipes.
