Speaking with ABC's "Nightline" in an interview to air Thursday night, Stewart says what Ray does isn't good enough for her.
"To me she professed that she cannot bake," Stewart says of Ray. "She just did a new cookbook which is just a re-edit of a lot of her old recipes, and that's not good enough for me. I really want to write a book that is a unique and lasting thing -- something that will fulfill a need in someone's library. So she's different, she's more of an entertainer than she is -- with a bubbly personality -- than she is a teacher like me. That's not what she's professing to be."
When asked about Stewart's comments, Ray says "It's true. It's 100 percent true," but adds the criticism doesn't upset her.
"Why would it make me mad?" Ray says. "When it comes to producing a beautiful, perfect, high quality meal, I'd rather eat Martha's than mine too."
