Tonya says she was shocked to see Tyler on her doorstop, but she's now grateful for all his help.

"We just couldn't believe it," she says. "The problem, of course, is he showed us what we were doing wrong. We had to live with that, but it came out all right."

Since Tyler left, Tonya says she's made several of his recipes—and says she's still working on perfecting some of them. "I think I burned his toasted coconut flakes," she says.

"Baby steps," Tyler says. "It's all right."
