A Rhubarb lover's delight! Rhubarb jam, pure and simple. This jam also freezes well, but it will probably get eaten up before making it to the freezer! Fabulous!
After you bring the jam to the boil, begin testing for the setting point by placing a small amount of the jam onto a cold plate. If it wrinkles when you push it with your finger, it is ready to be placed in jars. Be patient as sometimes it can take 20 to 30 minutes of boiling for the setting point to be reached.
