I'm wondering if sweet potatoes and buckwheat gnocchi exists.

Yesterday after shoveling around the front back side and roof I needed to rest. I went upstairs and tried to nap. That wasn't working. I flicked on the TV and caught my favorite Chef's TV show Chef at Home. Michael Smith was making a special dinner pan fried duck, home made gnocchi, and a green salad with special dressing. This morning my head is spinning with gnocchi ideas. I'm wondering if sweet potatoes and buckwheat gnocchi exists. Look what I found?
