Orange Marmalade

Ingredients

Directions

Prepare the oranges

  1. Boil the oranges until tender enough for a pin to pierce the skin.

  2. Grate half of the oranges to reduce bitterness.

  3. Cut the boiled oranges in half.

  4. Remove all the seeds.

  5. Scoop out the pulp.

  6. Cut the skins into thin strips.

Make the marmalade

  1. Dissolve the sugar in 1½ pints of water in a preserving jar and boil for 20 minutes.

  2. Skim the syrup well until clear.

  3. Add the pulp and strips of peel to the syrup and boil for 15 minutes.

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

Orange and sugar barely smell alike, yet cooks put them together in 19,212 recipes: they work on texture and structure more than aroma.

What each ingredient does

Seville oranges
Their peel and pulp supply the bitter flavour and pectin that help the marmalade set.
Lump sugar
Sweetens the marmalade and, as it concentrates, helps it set and keeps it preserved.
Water
Dissolves the sugar into a syrup that the fruit cooks in.

The step that matters

Skim the syrup well until clear. Skimming removes foam and cloudy particles from the dissolved sugar, so the finished marmalade looks clear rather than murky.
