Clear Orange Marmalade

Ingredients

Directions

Prepare the fruit

  1. Wash and wipe the oranges clean, then remove the rinds in quarters.

  2. Boil the rinds in a large quantity of water until tender.

  3. Drain the rinds and scrape off the white skin and fibers while warm.

  4. Pound the rinds to a paste.

  5. Blend the paste with the pulp and juice gradually to avoid lumps.

  6. Soak the seeds in ¼ pint of water for 1–2 hours.

  7. Mix the seed water into the paste.

Cook to a clear set

  1. Boil the mixture quickly without sugar for 15–20 minutes.

  2. Add half of the sugar and boil for 10–15 minutes.

  3. Add the remaining sugar and boil for another 15–20 minutes until thick and clear.

    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
Provide the bitter peel, pulp and juice that give marmalade its characteristic flavour and pectin.
Sugar
Sweetens the marmalade and, once dissolved and boiled, helps it set to a thick, clear gel.

The step that matters

Adding the sugar in portions. Sugar added to the fruit before it has softened can toughen the peel and slow pectin extraction. Adding it in stages after a quick boil helps the marmalade reach setting point with a clear, thick texture.
