Francis Lam is in the kitchen with cookbook author and Top Chef judge Gail Simmons to learn about her Key 3, the three go-to dishes she just can't do without - including the perfect fried egg sandwich. Chef, writer and photographer Michael Harlan Turkell traveled the world in search for unique vinegars for his new book, Acid Trip. He talks with Shauna Sever about his experiences, and discusses the equipment needed to make vinegar at home. Sous vide is an easy cooking technique that involves cooking sealed food in a precisely heated water bath. Molly Birnbaum, executive director of science at America’s Test Kitchen, explains the process and tells us about the winner of a recent sous vide equipment test. And The New York Times Magazine writer Tejal Rao opens her heart to love over a well-shucked oyster. Francis takes listener phone calls to talk about braising projects - large and small - cooking zucchini noodles, and he gets a fan's recipe for a ultra-savory umami powder.
