When asked in a previous interview where she finds inspiration for her recipes, Ina replied, “everywhere!”

“It comes from a remembered flavor — something that I had as a child. It comes from a friend. My friend Sarah Chase is an incredible cook and tremendous inspiration for me. She also writes cookbooks,” she once told Epicurious.

“It comes from something I ate in Milan or — I think you don’t get ideas by sitting at home and talking to yourself. I think you get ideas by getting out there. It comes from everywhere,” Ina continued. “It rarely comes from restaurants because restaurant food is a whole different category. It usually comes from something I ate at somebody’s house or a specialty food store or something like that.”
