Put all ingredients into blender and blend well. Add water until it is desired consistency. Let sit for flavors to blend.
I use approximations...this isn't a hard and fast recipe. Put in as much or as little as appeals to your individual tastebuds. I find silken tofu is best, regular still tastes good, but the finishe'd product isn't very smooth.
Can be used over a salad, to dip veggies in, or as a topping on potatoes. Has a somewhat sour cream taste to it.
