Tony Maws, the burger king and chef/owner of Craigie on Main and Kirkland Tap & Trotter, ventures into new territory with his latest invention: the Craigie on Main vegetable burger ($18). “We didn’t want this to taste like beef, but we did want it be savory and packed with umami,” Maws says of the dish that he worked on for more than a year and is currently served only on Tuesdays. A mixture of roasted mushrooms, fermented black bean powder, pomegranate molasses and tahini is added to a base of black beans, brown rice, lentils and egg for a savory patty that’s sandwiched between a housemade bun. Topped with feta, Maws’ secret sauce, lettuce, charred red onions and served with pickles, slaw and aioli, the burger’s flavors are bold and craveable—even for carnivores.
