Preserved Pumpkin

Ingredients

Directions

Prepare

  1. Cut the pumpkin into pieces about ⅓ inch thick and remove the skin.

  2. Weigh the pumpkin and use an equal weight of white sugar.

  3. Combine the pumpkin, sugar, and lemon juice in a pan and let it sit overnight.

Cook and preserve

  1. In the morning, transfer the mixture to a preserving kettle and cook until clear, skimming well.

  2. Add the small pieces of lemon peel, then strain the syrup through a jelly bag and pour it over the pumpkin.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: 2,3-butanedione (butter, sweet).

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Pumpkin
Provides the bulk of the preserve and its tender, soft texture once cooked.
White sugar
Sweetens the preserve and draws moisture out of the pumpkin to form a syrup.
Lemon juice
Adds acidity that brightens the sweetness and helps the preserve keep its flavor.

The step that matters

Cook until clear, skimming well. Cooking sugar with fruit or vegetable until the syrup thickens concentrates the sugar and sets the pieces, so stopping too early leaves a thin syrup. Skimming removes foam and impurities that would otherwise cloud the preserve and spoil its appearance.

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.
