if you are putting anything else sweet in like dried fruits or honey it probably will taste ok. personally my favorite thing to do is to cut dates in half stick and almond in each half and dip into melted carob.. it also works good with strawberries!
I would just add them to muffin or cookie batter. If the batter already contains sweetener, it should not matter that the chips aren't sweetened.
I have also used these to make carob frosting for cake or cupcakes. I just baked the carob chips in the oven until melted, then stirred in hot half-and-half and a little vanilla extract. Makes a yummy frosting even if the chips are unsweetened.
xenabyte I know what you mean - I hate bittersweet chocolate too - but I love frosting made with it (even unsweetened) as long as the cake it's on top of has sweetener in it. As long as it's rich and creamy, it kind of offsets the sweetness of the cake and you just taste the rich chocolate (or carbob!)
