This is a modified version of Ina Garten's Summer borscht that I found on foodtv.com. I have replaced whole fat sour cream and yogurt, with low fat. I also made it with 3 beets instead of 5, and prepared them in a pressure cooker. I eliminated the sugar from 1/4 cup, to 2 tablespoons. For flavor and texture, I added sauteed onion and carrots. And for authenticity, I prepared it with beef broth. Last, I increased the amount of beet liquid used, thus increasing the portion size.
