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

What each ingredient does

Kentish cherries
Provides the main body and bulk of the preserve's fruit flavour.
Raspberries
Add bright, aromatic fruit flavour and colour to the preserve.
Red currants
Contribute tartness and natural pectin that helps the preserve set.
White currants
Add acidity and pectin, balancing the sweetness of the sugar.
Granulated sugar
Sweetens the preserve and, with the fruit's acid and pectin, helps it gel and keeps it stable.

The step that matters

Stirring while the sugar boils. Sugar-rich fruit mixtures scorch easily on the bottom of the pan when boiling down. Constant stirring spreads the heat, prevents burnt flavour, and keeps the preserve from sticking as it thickens.

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.
