I found this dressing a couple years ago, and have been using it since. When I went to get a new bottle to replace the one I finished up, I grabbed a bottle from the same spot on the same shelf at the same grocer I have been buying from. Didn't notice the label change. There is a new recipe made with olive oil. It is not this zero calorie recipe with the great flavor. When I used it the following day, I nearly gagged. The new recipe needs to be avoided at all costs. Luckily I did find a bottle of the zero-calorie recipe hidden in the back of the shelf when I went back, but now that my bottle is getting low again, I am searching for the good stuff. I checked a few other stores around me, and all that do carry Walden Farms have switched to the new disgusting stuff.
So check the label carefully. If it is this zero-calorie recipe, you're good to go. This stuff is great. If it is the "new recipe" label, made with olive oil, run far and fast. I don't know how it passed anyone's taste test to say it is even edible. The olive oil one is utterly disgusting.
