We had a huge Costco pack of oranges that were starting to kick the bucket and it's always nice to find something to do with aging fruit.
I peeled and chopped six cups of fruit and thinly sliced the peel of one orange.
Then I combined the fruit and peel with six cups of sugar and six cups of water.
I brought the mixture to a nice rolling boil, added two packages of pectin and reduced until it reached a jam like consistency. I highly recommend using two packs of pectin. In my first batch I only used one and the jam didn't set. I had to reprocess it and add more pectin.
Pour into hot, sterilized jars and process in a hot water bath for 15-20 minutes depending on jar size.
