Marmalade, Orange, Crated

Ingredients

Directions

Prepare

  1. Grate the outer rind of the oranges and lemon.

  2. Scoop out the insides and remove the seeds.

  3. Bruise the pulp with ¼ cup of water through a sieve.

  4. Weigh the orange pulp and measure out an equal weight of sugar.

Cook

  1. Boil the orange pulp, sugar, and grated rind together until the rind is tender, about 30 minutes.

  2. Soak the grated rind in water to prevent clumping before adding it to the mixture.

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

What each ingredient does

Oranges
Pulp and rind supply flavour, bitterness and pectin that help the marmalade set.
Lemon
Adds acidity and pectin, which help the marmalade set and keep its brightness.
Sugar
Sweetens the marmalade and helps it set and keep by drawing water away from the fruit.

The step that matters

Boil until the rind is tender. The rind must soften fully during boiling, because its thick peel stays chewy if undercooked. Pectin from the pulp and rind helps the mixture gel as it reduces with sugar.
