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

What each ingredient does

Currants
Provide the main fruit body and tart flavor that the preserve is built on.
Sugar
Sweetens the preserve and, as it concentrates, helps it thicken and keep.
Raisins
Add concentrated sweetness and chewy texture to the preserve.
English walnuts
Add crunchy texture and a rich, slightly bitter nutty flavor.
Lemon juice
Adds acidity that brightens the flavor and supports setting.

The step that matters

Boil until preserve-like consistency. Pectin and sugar set only as water evaporates and the mixture concentrates. Stopping too early leaves it runny, while overcooking makes it stiff and may scorch the sugar on the bottom of the pot.

Swap the walnut
