Claire Saffitz, host of Bon Appétit’s Gourmet Makes series, has gained internet notoriety for her dogged reverse-engineering of America’s favorite snacks. Her videos have garnered millions of views on YouTube as fans both root for her success and relish in her relatable sighs of frustration along the way.

In the video above, Claire takes the Cut through a day in her hectic life — from shooting episodes at the Bon Appétit test kitchen and prepping for the upcoming Bon Appétit Hot 10 Party, to keeping her unruly, dairy-filled fridge organized.

Doing the Most is a special series about ambition — how we define it, harness it, and conquer it.
