Pumpkin Marmalade

Ingredients

Directions

Prepare the pumpkin

  1. Pare and cut the pumpkins into large pieces, removing the seeds with an iron spoon.

  2. Weigh the pumpkin pieces and use 1 pound of sugar for each pound of pumpkin.

  3. Grate the pumpkin on a coarse grater.

Make the marmalade

  1. In a preserving pan, combine the grated pumpkin, sugar, grated yellow rind of the orange or lemon, and the strained juice.

  2. Boil slowly, stirring frequently and skimming until it becomes a smooth, thick marmalade.

Jar

  1. Pour the warm marmalade into small glass jars or tumblers and cover with a double round of tissue paper and waxed paper.

The flavor team

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 orange barely smell alike, yet cooks put them together in 19,212 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

Ripe yellow pumpkins
Forms the bulk of the marmalade and provides its body and mild sweetness as it cooks down.
White sugar
Sweetens the marmalade and, as it cooks down, helps it set into a thick, spreadable texture.
Orange or lemon
Its grated rind adds aroma and its juice adds acidity that brightens the sweet pumpkin.

The step that matters

Boil slowly and keep stirring. Sugar and pumpkin thicken as water evaporates, but at high heat the sugar can scorch on the pan bottom and the mixture can burn. Slow boiling with frequent stirring lets moisture leave evenly and the marmalade reach a smooth, thick set.

Swap the pumpkin

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

  1. Vanillafits better
  2. Lemonfits better
  3. Figfits better
  4. Pumpkinthe original

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