This is an excellent sauce as an accompaniment to turkey or chicken dinners.  Commercial canned varieties are invariably full of sugar.

Liquid sweetener (sucralose or stevia) to equal 1 cup sugar (250 mL)
1/2 cup powdered erythritol or a bulk sugar substitute (125 mL)
1 1/4 cups water (300 mL)

In medium saucepan, dissolve liquid sweetener and erythritol in water; add cranberries. Over medium heat, bring to boil and cook until cranberries pop (about 20 minutes). Lower heat and simmer 10 minutes more. Allow to cool. Cover and refrigerate.
