These were good. I used one russet potato and one sweet potato (yam). They were both large and so I boiled them for about 40 minutes. I wasn't sure if they were supposed to be soft or if the grilling would finish cooking them. I think that I may have undercooked mine a little bit. Next time I would cook them until they were soft but still manageable for the grill because the grill didn't really cook them more. Loved the seasonings. Thanks Lynn for a fun and delish dish to make. Made for ZWT7 for the Emerald City Shakers.
