Just because its a feature in Call of Duty (or some other popular shooter game) doesn't mean its a guarantee for a Battlefield game. I've personally played Battlefield: Bad Company 2 and Battlefield 1942 prior to Battlefield 3 and it was perfectly fine even if you couldn't cook grenades. Sure, its a feature I would have liked, but then again, its not game-changing at the least, and is something I can deal with.
