Proof is a new podcast from America’s Test Kitchen, hosted by Bridget Lancaster. It goes beyond recipes and cooking to investigate the foods we love (such as deep-fried oreos and tiki drinks) and don’t love (like once-in-vogue celery and the meteoric rise of the grain bowl). We ask the big questions (where do food cravings come from?) and uncover the hidden backstories that feed your food-obsessed brain. Proof solves food mysteries, one story at a time.

New episodes air weekly on Thursdays.
