How do you make sugar free plum jelly?

Jam can't truly be "sugar free", as the fruits contain natural sugars, however, you CAN make "no sugar added" jams. You simply follow your standard recipes, and replace the amount of sugar it calls for with the proper amount of artificial sweetener. The sweetener you choose will have a conversion chart on the packaging. Do NOT substitute the same quantity of artificial sweetener for sugar. For instance, if it calls for 1 cup of Sugar, you would add, say, 1 tsp. of Splenda (this can vary, depending on the sweetener).
