This is by far the easiest recipe I have found for strawberry jam without using a pectin. The jam is soft, spreadable and delicious.

To test for jelling
Place three plates in a freezer... after about 10 minutes of boiling place a tsp of the liquid of the jam onto the cold plate. Return to freezer for a minute. Run your finger through the jam on the plate... if it doesn't try to run back together (if you can make a line through it with your finger) it's ready to be canned!
