Last night we made the Black Bean Burgers from Veganomicon, with the cilantro sour cream. Served on fresh buns with frozen french fries. I dipped my fries in the cream.
The texture of the burgers was great. I felt they were lacking on spices (1 tsp chile powder and 1/2 tsp cumin) so next time I will tinker with those quite a bit.
I liked the flavor of the sour cream but it was a bit too watery for the burgers. Next time I would use half silken tofu and half soft tofu to make it a bit thicker.
