I would nix the idea of using teak. It works well on a boat because it handles the wetness well, but teak will washout to gray over time even with some finish over it.. I am not sure you would want that in a kitchen.
I would go with yellow birch.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
