Orange Marmalade

Ingredients

Directions

Prepare the fruit

  1. Weigh the sugar and oranges.

  2. Score the skin of the oranges and remove it in quarters.

  3. Boil the quarters in a muslin bag in water until soft and easily pierced.

  4. Cut the rind into chips about 1 inch long and as thin as possible, removing any excess white pulp.

  5. Split open the oranges, scrape out the pulp and juice, discarding the white pith and seeds.

Make the marmalade

  1. Make a syrup by boiling the sugar and water until clear.

  2. Add the chips, pulp, and juice.

  3. Boil the marmalade for 20 minutes to ½ hour, removing any scum that rises.

What each ingredient does

Seville oranges
Provide the bitter peel and pectin-rich pulp that give marmalade its flavour and set.
Sugar
Sweetens the marmalade and helps it set as the syrup thickens.

The step that matters

Boiling the marmalade. Boil long enough for the syrup to reach setting point, since too little boiling leaves it runny. Removing scum keeps the finished marmalade clear and clean-tasting.
