This mobile kitchen operated by two local culinary pros, Carrie Summer and Lisa Carlson, dispels misconceptions about mediocre street food every Saturday morning during the Mill City Farmers' Market and Sundays at the Kingfield Farmers' Market. Summer handles the sweets, and Carlson, the chef at Spoonriver, handles the savory offerings, and both use many local, organic ingredients from the market. Favorite foods include the bison burger, with a gamey, peppery flavor that's tasty enough to eat undressed--but don't, the homemade condiments are too good to miss. The ribs, though impossible to eat with a plastic spork, are fantastic, as is the grilled asparagus with frothy lemon aioli. The Indian-spiced mini donuts are good enough to forget all about the health kick that brought you to the mostly organic, upscale market in the first place, and the crème brûlée--topped with caramelized bananas, triple-chocolate coconut cookies, and softly whipped cream--is the best version in town. Trailer treasure, indeed!
