The Cooking Channel has been filming at some foodie hot spots around Portland, South Portland and Cape Elizabeth this week.

A film crew for “a national TV show” was at the Holy Donut on Park Avenue in Portland on Tuesday, according to Jeff Buchwalter, manager of the doughnut shop’s second location on Exchange Street and brother-in-law of owner Leigh Kellis. He said Kellis had to sign a nondisclosure agreement, so he couldn’t provide any more details.

But Sonja Swanberg, one of the owners of Scratch Baking Co. in South Portland, said a show from the Cooking Channel filmed at her bakery Wednesday. She could not provide any further details because she also had to sign a nondisclosure agreement. “It was a very hot day, but we had a good time,” she said. “It was definitely a very interesting experience.”

Debi Mazar and her husband, Gabriele Corcos, hosts of the Cooking Channel show “Extra Virgin,” filmed at The Well at Jordan’s Farm in Cape Elizabeth all day Tuesday for a show that is supposed to air in January, according to The Well’s Facebook page, and the couple visited Portland Lobster Co. on Wednesday.

Mazar posted a photo of herself picking flowers at The Well on Twitter and Instagram, and said the meal she had there was “one of the best meals I’ve ever had.”

Mazar also posted a selfie taken at the Portland Head Light in Fort Williams Park and said it was her first time visiting the Portland area. She wrote: “Filming in Portland Maine! The air is so fresh and it’s really like a postcard!”
