Pumpkin Preserves

Ingredients

Directions

Prepare

  1. Remove the rind from the pumpkin and cut it into pieces.

  2. Weigh the pumpkin and measure out an equal weight of loaf sugar.

  3. Add ½ cup of lemon juice for each pound of sugar and pour it over the pumpkin.

  4. Cover and let it sit overnight.

  5. The next day, add the peels of 1 or 2 lemons.

Cook and preserve

  1. Boil the pumpkin until tender and clear, but not broken.

  2. Remove the pumpkin and place it on broad dishes to cool.

  3. Transfer to jars or tumblers and pour the syrup over the pumpkin.

  4. Once cool, cover with brandy paper and secure tightly.

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 and turns tender and translucent during boiling.
Loaf sugar
Sweetens the dish and, as a syrup, preserves the pumpkin by drawing out moisture.
Lemon juice
Adds acidity that brightens the flavour and helps the pumpkin hold its shape.

The step that matters

Boil until tender and clear, but not broken. Boiling too hard or too long breaks the pieces down into mush. Gentle simmering lets the sugar syrup penetrate and the pumpkin turn clear while keeping its shape.

Swap the pumpkin

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

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

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