To Make Orange Marmalade

Ingredients

Directions

Prepare the peel

  1. Grate the yellow zest from the oranges and set aside.

  2. Cut the orange skins into quarters, remove the inner white part, and slice the remaining peel into thin chips.

  3. Place the chips in a pot and cover with cold water.

  4. Boil until tender.

Make the marmalade

  1. Extract the juice from the oranges using a sieve and set aside.

  2. In another pot, heat the sugar until it dissolves and comes to a boil.

  3. Add the orange juice and chips to the boiling sugar, stirring constantly.

  4. Boil quickly until the mixture jellies, about 10 minutes, stirring to prevent sticking.

  5. Test for readiness by placing a small amount on a saucer; it should wrinkle when cooled.

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).

  2. Sugar + orangetop 20% of all pairs

    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
Provide the peel and juice that give the marmalade its bitter flavour and pectin for setting.
Lump sugar
Sweetens the marmalade and, as it concentrates, helps the mixture set into a jelly.
Cold water
Covers the peel chips so they soften evenly while boiling until tender.

The step that matters

Boiling until the mixture jellies. The sugar and juice must reach a rolling boil long enough for the pectin and acid to set the mixture. Undercooking leaves it runny, while overcooking makes it stiff and dark. The saucer test shows whether it has reached the setting point.

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.
