Four years ago, we had Thomas McNaughton on the show, talking about his new concept, Flour + Water Pizzeria in the Mission District in San Francisco. Since the pandemic, he and his co-Chef/Culinary Director, Ryan Pollnow, moved and expanded the operation, tweaking the recipe, and deciding to set up a commissary in the new store that will ultimately support additional stores. Meanwhile, they operate a sit-down pizzeria in front and a slice shop in the back. That’s where I met Pollnow, to talk about the evolution of their pizzeria, and how they nailed one of the best gluten free slices I’ve ever had.
