_FOOTSIE:But she never put baking soda in it (don't understand why you would)
You can leave out the baking soda and it is still delicious. I think it is the chemical reaction of the vinegar and the baking soda (think Jr. High science - volcano experiment lol) that makes the sauce really light and creamy smooth.
I never measure either - in fact, I had to go look at the recipe to see what the measurements were so that I could post the recipe. I always add and taste, add and taste, until it is just right. LOL , that is the kind of cook I am - I use recipes as a starting point and I go from there. I love to tweak and taste as I go along.
This is also delicious made with low-fat sour cream and splenda (replace sugar with equal measure of Splenda).
