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

What each ingredient does

Plums
Provide the main fruit flavor and body of the preserve as they cook down.
Sugar
Adds sweetness and helps preserve the fruit while it thickens.
Lemons
Their acidity helps pectin in the fruit set the preserve.
Oranges
Add citrus aroma and acidity, with the rind contributing fragrant oils.
Raisins
Add concentrated sweetness and a chewy texture.
Pecans or english walnuts
Add crunch and a toasty, rich flavor that contrasts with the soft fruit.

The step that matters

Cook for the full time. The mixture thickens as water evaporates and sugar and fruit pectin set together. Acid from the citrus helps the pectin gel. Stopping early leaves the preserve runny, while cooking too long can scorch the sugar and darken the flavor.
