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

What each ingredient does

Kentish cherries
Provide body, sweet-tart flavor, and fruit pulp for the preserve's texture.
Raspberries
Add bright aroma and fruity flavor to the preserve.
Red currants
Contribute natural pectin and acidity that help the preserve set.
White currants
Contribute natural pectin and acidity that help the preserve set.
Granulated sugar
Sweetens the preserve and helps it thicken and keep its set.

The step that matters

Stir in the sugar and keep stirring while boiling. Once sugar is added, the mixture is thick and sugar can scorch on the hot pan bottom, giving a burnt taste. Constant stirring spreads heat evenly and keeps the jam from sticking while the sugar dissolves and the preserve 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.
