Cranberries, like most berries, are a low sugar fruit. A whole 12-ounce bag of fresh cranberries – that’s what they sell in my grocery store, at any rate – has 167 calories, with 43 grams of carb, 14 of which are fiber. So that whole bag has 29 grams of usable carb in it. Making low carb cranberry sauce is quick and easy. Really, really quick and easy. Dana Carpender shows us how.
