DeborahS Orange Pineapple Marmalade - oranges

Method

• Thinly slice oranges in a mandolin or salad slicer (if there are big chunks, slice them thinly with a knife), also do this with the lemon, removing any seeds. Put slices in a big pot and add pineapple and water. Bring to a boil. Once boiling, reduce the heat to maintain a rapid simmer and cook, stirring frequently, for 40 minutes or until the fruit is very soft.
• While the fruit is cooking, prepare your jars and lids, sterilizing all tools. Place a plate in the freezer, you will test a drop of jam on it later.
• Add the sugar and stir frequently until it reaches 222-223 degrees, or about 40-45 minutes. It should be thick and a darker color. Take out plate from freezer and put a small spoonful of jam on it, let sit for 30 seconds. Tilt the plate and if it's runny, it's not set and needs to be boiled longer. If it barely moves and is a thick gel, the jam is ready to be canned.
• Put hot jam into hot, sterilized jars. Put on lids and rings, put in a boiling bath for 10-15 minutes. Sit on rack or thick towel to cool and make sure all the tops are firmly sealed down, with no bump in the middle. Enjoy!
