Pumpkin Preserve

Ingredients

Directions

Prepare the pumpkin

  1. Remove the rind and seeds from the pumpkin and cut it into 1-inch cubes.

  2. Steam or cook the pumpkin in water until tender but not broken, then drain carefully.

  3. For each pound of pumpkin, use 1 pound of sugar, 2 lemons, and 2 ounces of ginger root.

Make the syrup

  1. Tie the ginger in a bag, remove the yellow skin from the lemons, discard the white part, and slice the pulp, removing all seeds.

  2. Cook the ginger, lemon skin, and lemon slices in a quart or more of water until strongly flavored.

  3. Add the sugar and boil until it forms a syrup that just covers the pumpkin.

Cook and store

  1. Add the pumpkin to the syrup and boil slowly until the pumpkin is transparent.

  2. Store the preserve in jars and reduce the syrup until very thick.

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

What each ingredient does

Pumpkin
Forms the bulk of the preserve and turns translucent as it absorbs the syrup.
Sugar
Sweetens the preserve and, as it thickens, creates the syrup that preserves the fruit.
Lemons
Add acidity and brightness that balance the sweetness of the syrup.
Ginger root
Adds aroma and a warm, spicy flavor to the syrup.

The step that matters

Boil the pumpkin slowly in the syrup. Boiling vigorously can break the pumpkin pieces apart before they become transparent. Slow simmering lets sugar syrup gradually replace the water in the cubes, which is what makes them clear and firm.

Swap the pumpkin

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

  1. Orangefits better
  2. Limefits better
  3. Mangofits better
  4. Pumpkinthe original

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