We wanted the Baconnaise lite after seeing the product on Oprah. We looked forward eagerly to the  prospect of that great bacon taste. The decision in our house was 1 for and 1 not so. The taste is there, the "greasy" taste was also. I won't buy the product again.

I don't like using artificial sweeteners because of the chemicals and because they don't taste good. I am a caregiver for my diabetic dad, and once I discovered this product I was hooked, except that it is hard to find where I live. When I found it at Amazon I put it on auto ship so I don't run out.  The price has gone up a lot since I first found it on Amazon, however, it still costs more in stores if and when I can find it there. I make limeade with this which I keep on hand at all times. In a gallon container of water I add 1 cup of lime juice and 2tbsp. of stevia powder. It is refreshing and almost no calories and no chemical aftertaste.  My dad uses the stevia in his coffee and his oatmeal. I haven't tried cooking with it although I know they make one designed for baking, which I'll possibly try this winter.
