The Blue Ribbon BBQ Trailer doesn’t move much. Since May, it’s been camped near an industrial park in Needham, serving a condensed version of the menu offered at the brick-and- mortar locations in West Newton and Arlington. Smoke permeates everything from the meats to the cornbread, thanks to the onboard Texas-made smoker bought by owner Geoff Janowski, who was inspired by trailers during a trip to the Lone Star State. The Kansas City burnt ends sandwich ($8) rises to the top, served on a plain white bun, meat shredded while not overly-torched. A pulled chicken sandwich ($8) is surprisingly chunky, and the most smoky meat on the menu. Memphis dry-rubbed pork ribs ($13 third-rack platter) are extremely fatty, but colossal. And lurking like a prize at the bottom of a cereal box, a piece of white bread soaks up the flavors of the meat platters.
