Preserved Pumpkin

Ingredients

Directions

Prepare the pumpkin

  1. Boil the pumpkin until tender enough to pierce with a straw.

  2. Drain the pumpkin and weigh it.

  3. For every pound of pumpkin, use one pound of sugar and one lemon for every four pounds of pumpkin.

Make the syrup

  1. Slice the lemon and combine it with the sugar and ½ cup of water for each pound of sugar.

  2. Boil the mixture until a clear syrup forms, removing any scum that rises.

Preserve and store

  1. Add the pumpkin to the syrup and boil gently until the pumpkin is clear.

  2. Cool the preserve and store it as you would other preserves.

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

What each ingredient does

Pumpkin
Is the main body of the preserve, becoming tender and translucent as it cooks in syrup.
Sugar
Sweetens the preserve and, at high concentration in syrup, helps keep it stable and shelf-stable.
Lemon
Adds acidity that brightens the flavour and helps balance the sweetness of the syrup.

The step that matters

Boiling the pumpkin in the syrup until clear. Gentle boiling lets sugar slowly replace the water inside the pumpkin pieces. Boiling too hard can break the pieces apart and make the syrup cloudy, so the pumpkin should be cooked gently until it turns translucent.

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.
