Query: Chemical aftertaste

Give Walden Farms credit for making a no-carb sauce. It's just a shame it doesn't taste better. Still, I do buy it on occasion and mix it with other tastier sauces to lower the over all carb content. However, the smoke taste is so overwhelming that more than a proportion of 1:4 leaves only the taste of this product in your mouth. This product cannot begin to compare with the taste of the now-defunct Kraft's low-carb barbecue sauce. Mostly, I make my own low-carb sauce from scratch and then just add a bit of this to get the smoke taste, but too much and even the best batch of homemade sauce is ruined. However, if you are on an extreme low-carb diet (such as Dr. Bernstein's) this may be the only product that fits.
