Super cook? I'd start with Luck, Serendipity, Gunslinger, Trained by a Master, Throwing Art, world class unarmed skills, Stealth, Tactics, and anything else fitting for a
former SEALS one man army.
Jokes aside, Pyramid #3-105: Cinematic Magic has the article Gourmet Alchemy which I think is perfect for what you want.
On another note, I recall Kromm mentioning a player he had once that was a mage specialized in food magic. He'd use Seek Food to locate enemies and carried tubes of spice with corks on both sides that could be used as blowpipes.
