There’s a hot dish of celebrity drama brewing in America’s TV kitchen. The high priestess of homemaking, Martha Stewart, issued a verbal smackdown to cookin’ counterpart Rachael Ray in an interview airing on ABC’s Nightline Thursday evening (11:30PM ET).

Stewart quips that Ray’s efforts are “not good enough for me” and that the quirky author, infamous for her embrace of catchphrases like “Oh my gravy!” and “Delish!,” is a nauseating rip-off, who recast old recipes for her 30-minute meal books.

Ouch.

Perfectionist Stewart recently appeared on Ray’s popular daytime show, but she insists things are far from “Yum-O” between the two TV chefs.

“She professed that she cannot bake (and) 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,” Martha says. “I mean, I really want to write a book that is a unique and lasting thing. Something that will really fulfill a need in someone’s library. So, she’s different. She’s more of an entertainer than she is… a teacher, like me.”

Rachael has taken the high road after learning what Martha said.

“Why would it make me mad?” Ray told ABC. “Her skill set is far beyond mine. That’s simply the reality of it. That doesn’t mean what I do isn’t important, too … I don’t consider it needling. I really just think she’s being honest.”
