MIAMI BEACH, Fla. — America might not know what to make of a celebrity chef as comfortable quoting philosophers as corralling reality cooking show contestants.

And Nigella Lawson is at ease with that. “Today, it’s all about marketing and people want to know where to place you,” Lawson said. “And I suppose I just don’t care about that.”

Lawson garnered attention for telling the producers of her latest television venture, “The Taste” on ABC, that they could not retouch images of her to reduce her belly.

“I don’t need that to be mediated by any other person,” she said.
