Pumpkin, Preserved

Ingredients

Directions

Prepare the pumpkin

  1. Pare, halve, and remove seeds from the pumpkin, then cut it into thin slices about the size of your palm.

  2. Weigh the slices and mix in 1 pound of powdered sugar, the juice of 2 lemons, the peel of 1 lemon, and ½ teaspoon of ground ginger.

  3. Layer the pumpkin slices in a large dish, sprinkling sugar between layers, and pour the lemon juice over the top.

  4. Let the mixture sit for 2-3 days.

Cook the syrup

  1. Transfer the mixture to a preserving pan, adding 1 cup of water for every 3 pounds of sugar used, and boil gently until the slices are tender.

  2. Pour the mixture into a bowl and cover for 6-8 days.

  3. Discard the bag containing the ginger.

  4. Strain the syrup and boil it again until thick, then pour it over the pumpkin slices.

Pack and store

  1. Pack the pumpkin into jars and cover with paper dipped in egg white.

  2. Store in a cool, dry place.

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

What each ingredient does

Pumpkin
Forms the body of the preserve, softening during boiling until tender.
Powdered sugar
Draws water out of the pumpkin and sweetens it, helping preserve the slices.
Lemon juice
Adds acidity that brightens the sweetness and helps preserve the pumpkin.
Ground ginger
Adds warm, spicy aroma to the syrup.

The step that matters

Boil gently until the slices are tender. Gentle heat softens the pumpkin's cell walls while keeping the slices intact. Vigorous boiling can break the slices apart and make the syrup cloudy.

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.
