Orahgb Marmalade

Ingredients

Directions

Prepare the peel

  1. Grate the rinds of the Seville oranges lightly.

  2. Cut the grated rinds into quarters, removing the flesh.

  3. Use a small spoon to remove the pips and loose inner skin from the flesh.

  4. Soak the rinds in cold water overnight.

  5. Boil the rinds for 20 minutes, changing the water halfway.

  6. Once tender, drain the rinds.

  7. Slice the rinds thin.

Make and jar the marmalade

  1. Add 8 ounces of rinds for each pound of pulp and juice.

  2. Add 1.5 pounds of sugar.

  3. Boil the mixture quickly for 30 minutes, skimming as needed.

  4. Pour the marmalade into jars.

What each ingredient does

Seville oranges
Their peel and pectin-rich pulp give the marmalade its bitter flavour and set.
Sifted sugar
Sweetens the marmalade and helps it set when boiled with the fruit.

The step that matters

Boil the mixture quickly for 30 minutes. Rapid boiling drives off water and concentrates the sugar and pectin so the marmalade sets. Skimming removes scum that would cloud it.
