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

What each ingredient does

Pumpkin
Provides the bulk of the preserve and its body as it cooks down.
Sugar
Draws moisture out of the pumpkin and, with cooking, thickens the preserve while adding sweetness.
Oranges
Add acidity and aroma from their juice and rind.
Lemons
Add acidity and aroma from their juice and rind.

The step that matters

Cook until it thickens. Sugar and pumpkin must be cooked long enough for the liquid to reduce and the sugar to concentrate, which sets the preserve. Stopping too early leaves it runny, while overcooking can scorch the sugar on the bottom of the pan.

Swap the pumpkin

How well each one fits the dish's main ingredients (sugar, orange, lemon):

  1. Limefits better
  2. Vanillafits better
  3. Blueberryfits better
  4. Pumpkinthe original

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