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

What each ingredient does

Plums
Provide the fruit, pectin and sugar-free bulk that cooks down into the jam's body.
Bitter almonds
Add a distinctive aroma that complements the fruit's flavor.

The step that matters

Cook until the mixture thickens. Stirring frequently over medium heat prevents scorching on the bottom of the pot, and the jam must be cooked long enough for its natural pectin and sugar to set as it cools.

Swap the vanilla

The recipe marks vanilla as optional. How well each one fits the dish's main ingredients (plum, almond):

  1. Apricotfits better
  2. Peachfits better
  3. Figfits about as well
  4. Vanillathe original

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