Old-Fashioned Seville orange marmalade

Method

1. Wash the fruit, cut in half and squeeze out the juice. Remove the membrane with a spoon, put with the pips and tie them in a piece of muslin. Slice the peel finely or coarsely, depending on how you like your marmalade. Put the peel, orange and lemon juice, bag of pips and water into a non-reactive bowl or saucepan overnight.

2. Next day, bring everything to the boil. Cover and simmer gently for about 1 1/2 hours until the peel is really soft. Then cook uncovered until the liquid is reduced to between 1/3 - 1/2 of the original volume (30 minutes approx.). Squeeze all the liquid from the bag of pips and remove it.

3. Add the warmed sugar and stir until all the sugar has been dissolved. Increase the heat and bring to a full rolling boil rapidly until setting point is reached 5-10 minutes approx. Test for a set, either with a sugar thermometer (it should register 104˚C/220˚F), or with a saucer. Put a little marmalade on a cold saucer and cool for a few minutes. If it wrinkles when you push it with your finger, it's done.

4. Allow marmalade to sit in the saucepan for 15 minutes before bottling to prevent the peel from floating. Pot into hot sterilized jars. Cover immediately and store in a cool dry dark place.

5. Note: The peel must be absolutely soft before the sugar is added, otherwise when the sugar is added it will toughen the peel and no amount of boiling will soften it.
