More Jam!

Help!  I can't stop making jam!  I had some friends taste test the watermelon jam this week.  They really liked it and told me not to change a thing!  I did however add some apple to the watermelon as I didn't think it was jelled enough and the apple has natural pectin in it.  I am hoping that will make it jell better.  I stopped at Aldi to do some grocery shopping and they had berries on sale, so I bought some.  After a trip to Meijer for more jelly jars, I made some blackberry and tripleberry this afternoon.  Peach Jam has always been my favorite, but.....the tripleberry is outstanding!  My family and friends better like jam, because that is what everyone is getting for Christmas.
