what other animal cooks their food at all?
Some australian raptors will deliberately spread wildfires to hunt. So they probably cook some food, but it's not intentionally for that reason.
Others in captivity, for instance: Chimps Are No Chumps: Give Them An Oven, They'll Learn To Cook
Many (crows, racoons, probably more) will use water to soften food, which is kinda similar. Control of fire I think is too difficult for proper cooking.
