Preserved Pumpkins

Ingredients

Directions

Prepare

  1. Select a sweet pumpkin, halve it, remove seeds, and peel the rind.

  2. Cut the pumpkin into neat slices and weigh it.

Layer and rest

  1. Layer the pumpkin slices in a pan, sprinkling sugar between layers.

  2. Pour lemon juice over the top and let it sit for 2-3 days.

  3. Transfer to a pan and let it sit for a week.

Cook and finish

  1. Boil the mixture, adding ½ pint of water for every 3 pounds of sugar, until the pumpkin is tender.

  2. Drain off the syrup, boil it until thick, skim, and pour it boiling over the pumpkin.

  3. Optionally, boil bruised ginger and thin lemon rind in the syrup for flavor.

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; cooking softens it until tender while the slices hold their shape.
Loaf sugar
Draws water out of the pumpkin and forms a thick syrup that preserves it and adds sweetness.
Lemon juice
Adds acidity that brightens the flavor and helps preserve the pumpkin.

The step that matters

Boiling the syrup thick and pouring it boiling over the pumpkin. Boiling the syrup down raises its sugar concentration, which helps preserve the pumpkin. Pouring it on while boiling keeps the fruit hot and helps the syrup soak in evenly.

Swap the lemon

The recipe marks lemon as optional. How well each one fits the dish's main ingredients (pumpkin, sugar, ginger):

  1. Vanillafits better
  2. Cherryfits better
  3. Coconutfits about as well
  4. Lemonthe original

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