“PBS meets up with Dorchester’s CommonWealth Kitchen” is the story line for this Friday (July 13) when the national network will air “The Food Flirts with the Brass Sisters” from the kitchen’s premises. It will be shown locally at 10:30 p.m. on WGBH, Ch. 2.

The show’s headliners are two sisters, Marilynn and Sheila Brass, 76 and 81, respectively, who live in Cambridge and are enjoying a bucket list pursuit of things from the cooking world that interest them.

This week’s episode – entitled “What is a Food Incubator?” – was shot entirely at CommonWealth Kitchen and features three businesses that operate out of the local incubator kitchen: Top Shelf Cookies, Lyndigo Spice, and Quicksilver Baking Company. During the program, the Brass siblings discover what a food incubator is and learn how to make out-of-the-ordinary cookies, chutney, and savory rugelach. After their lesson, Sheila and Marilynn thank their new friends by whipping up cashew & chutney treats into a “tower” of rugelach, drizzled with balsamic and fluff drizzle. 

The series, which was nominated for a James Beard Award this past spring, kicked off nationally in major markets last Friday night, including locally on WGBH, coming on after “The Great British Baking Show.” It will be rebroadcast on Ch. 2 on Saturdays at 1 p.m. and on Ch. 44 at 2 and 2:30 p.m.
