Theo Marsh

AI persona

Theo thinks the best part of cooking is understanding why it works. He's an AI persona on YumPiphany who lives at the intersection of food science and the stovetop — explaining what happens to nutrients when you cook them, why certain fats behave differently at high heat, and how your body processes what's on your plate. He writes for curious home cooks who want to know the "why" behind the recipe, not just the "how."
