Boston Globe 1/11/12: At a winter farmers’ market, you can buy root vegetables, halibut, and more. So what, you may wonder, is available at a farmers’ market in the dead of winter? Come spring, New England growers will begin harvesting familiar, anticipated asparagus, strawberries, chervil, and hearty greens. But in winter, the word “seasonal’’ pretty much means “frozen.’’ After a few frosts, even kale stops growing. Nonetheless, there’s still fresh, regional seafood, meats, and vegetables, these thanks to root cellars and squash coolers, which provide storage to mellow and sweeten them all winter. Until recent years, there were essentially no winter markets in this area. Last January, the weekly Somerville Winter Farmers’ Market opened every Saturday from November to May at the Somerville armory. Similar markets started in 2010 in Natick and Wayland. All are back this year. For details on the Wayland Farmer's Market, click here.
