"Saw this in the magazine and thot it would be healthy and easy. It certainly was, but it did not get "thick and creamy". I followed the recipe pretty much as directed, with the exception that I used spinach instead of the kale (grocery store was out of it), and the parm rind I used was a 1" by 2" piece---was it not big enough? Also it was actually Parmigiano-Reggiano, what I had on hand.
Anyway it was still very good, though thin and not thick.
