The flavor of these is fantastic. After 50 minutes, the potatoes were still a little crunchy, and we didn't know whether that's the way they ought to be or they were still underdone, but the texture was the main topic of conversation and we all would have preferred them softer. Made for Pick A Chef.

These were a hit. I used the grater attachment on the food processor or I would of been there all day grating. Thanks for posting.
