Orange Marmalade

Ingredients

Directions

Prepare the peel

  1. Pare off the yellow skins of the oranges, minimizing the white skin beneath.

  2. Cut the peels into small strips, then cut across to make smaller pieces.

  3. Place the peels in a pan and cover with water.

  4. Boil until soft.

  5. Strain the water through a sieve and set the peels aside.

Prepare the pulp

  1. Quarter the oranges, scrape out the pulp and juice into a dish, discarding the white skins, films, and seeds.

Make and jar the marmalade

  1. Combine the pulp, juice, and peels in the pan with the sugar.

  2. Stir until boiling.

  3. Boil for 30 minutes.

  4. Skim thoroughly.

  5. Pour the marmalade into jars.

  6. Once cool, cover the jars.

  7. Set aside for use.

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: acetal (cream, earthy).

    Shared aroma: beta-damascenone (apple, rose).

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

Bitter oranges
Supply the peel, pulp and juice that give marmalade its bitter flavor and pectin-rich body.
Sugar
Sweetens the bitter fruit and, when boiled, helps the marmalade thicken and set.

The step that matters

Boil until the marmalade sets. Sugar and pectin only gel when the mixture reaches a high enough concentration at a boil. Stopping early leaves a runny marmalade, while boiling too long can make it dark and stiff.

Swap the bitter orange

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

  1. Vanillafits better
  2. Lemonfits better
  3. Figfits better
  4. Bitter orangethe original

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