Ingredients

Directions

Prepare the fruit

  1. Cut the Seville oranges into quarters and remove the pulp into a basin.

  2. Pick out the seeds and skins.

  3. Soak the outsides in water with a little coarse sea salt overnight.

  4. Boil the soaked outsides in spring water until tender.

  5. Drain the outsides and slice them thinly.

Cook the marmalade

  1. Combine the slices with the pulp.

  2. Add 1½ pounds of double-refined sugar for every pound of pulp.

  3. Boil the mixture for 20 minutes, stirring gently to avoid breaking the slices.

  4. If not clear, simmer for an additional 5-6 minutes while stirring.

  5. Once cooled, transfer the marmalade into glasses.

    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
Supply the bitter peel and pectin-rich pulp that give marmalade its flavour and set.
Double-refined sugar
Sweetens the marmalade and helps it set into a gel as it cooks.

The step that matters

Boil the mixture for 20 minutes, stirring gently. Gentle stirring keeps the peel slices intact while the sugar dissolves and the pectin sets. Vigorous stirring breaks the slices apart and clouds the marmalade.
