In her new memoir, “Accidentally on Purpose,” Kristen Kish reflects on her childhood as a Korean adoptee in Michigan, coming out as gay in her late 20s, winning Season 10 of “Top Chef” and struggling with anxiety.

Yet Kish, who now hosts the Bravo competition series, is known for her laid-back interactions with contestants. “If my anxiety level was at a million growing up and being a young adult, it is certainly now in the hundreds,” she said. “It has drastically reduced because I’ve given time and energy to managing it in the best way I can.”

Kish, 41, in her book recounts an upbringing filled with meatloaf, casseroles and Sunkist candies. Such down-to-earth predilections have stuck with her despite her upscale culinary career.

“People ask what my guilty pleasure food is,” she said. “I don’t feel any guilt around anything. I want it, I like it, it’s delicious — I have no shame.”

In a phone interview last month, the globe-trotting restaurateur shared her favorite travel snacks, how she keeps in touch with her parents and the thing you’ll probably see her doing while she’s cooking. These are edited excerpts.

Fit Joy Pretzels

One of my favorite airplane snacks. The honey mustard flavor is specifically glorious, especially when you’re flying — you know how they say your taste buds go a bit muted. These are salty, there’s enough sweetness from the mustard, and the crunch is exceptional. I would rather eat five little packs of these over one meal they’re offering.
