Just baking them in an oven. If I start from frozen and just increase the cook time, should it come out alright or are there consequences for this kind of behavior?
Should be fine. If I really were set on not defrosting them first in a pot of water (shouldn’t take that long, maybe an hour), I would just start them in a cold oven. It’ll take longer to finish, but they should be fine, as long as you are doing a longer, slow-cooked style of ribs.
I didn’t even know that you could get ribs from Alaska. Ribs are usually more associated with non-frozen states like Texas.
