Step 1

Place orange and water in a large glass or ceramic bowl. Cover with plastic wrap and leave to stand overnight.

Step 2

Transfer to a large saucepan. Bring to the boil over medium heat. Reduce heat and simmer for 1 hr or until reduced by about one-third.

Step 3

Cool slightly, then measure the mixture and add 1 cup of sugar per cup of fruit mixture. Stir over low heat until the sugar dissolves. Increase heat to medium-high and bring to the boil. Cook, skimming any dense froth from the surface with a large metal spoon, for 45 mins or until setting point is reached (see tips).

Step 4

Spoon into warm sterilised jars (see tips). Seal and label.
