I think the crash hots were one of the first things I posted here.
They're great and you can season them any way you like.
I don't do anything to roasted red potatoes before they go in the oven other than to cut them into chunks, toss in olive oil and S&P. They come out fine.
However, I've roasted red potatoes leftover from a crawfish boil and when they are pre-cooked (all the way), they are creamier on the inside and still crispy on the outside. I've sometimes cooked them in a bowl of water seasoned with crab boil in the microwave before roasting when I want that flavor. Either way, they work for roasting, though.
