Make your own marmalade
In a medium saucepan, add all the ingredients.
Stir until combined over medium heat.
Attach candy thermometer to the pan.
Cook for 20-30 minutes or until the temperature reaches 220 degrees F/104 degrees C on the candy thermometer.
Skim any foam that is on the top.
Transfer the hot marmalade to a pouring jug to make it easier to transfer to jars.
If you don't have a candy thermometer, place a small plate in the freezer for an hour before you start. To test if the marmalade is ready, drop a little onto the plate and if it gels, it's ready.
To sterilize the jars, wash with warm soapy water and rinse well. Arrange the jars and lids onto a baking sheet and leave in a preheated, 175 degree F/80 degree C oven for 25 minutes. Or, boil the jars and lids in large saucepan of boiling water for 15 minutes. Allow to dry completely.
