We take America's Test Kitchen's inquisitive and relentless approach to telling unexpected, funny, and thought-provoking narratives about food and drink. This is not a recipe show. And this is not a show about celebrity chefs or what they like to eat. Proof plunges into history, culture, science, and the psyche to uncover the hidden backstories that feed your food-obsessed brain. Hosted by Kevin Pang. A production of America's Test Kitchen.
