Dark chocolate fans who normally shun milk chocolate can now enjoy Cocoa Metro Dark Drinking Chocolate ($5 for 32 ounces), made with Belgian Callebaut natural cocoa, and plenty of it. It tastes richer, thicker, and more intensely chocolaty than most other chocolate milks. Even made with 2 percent low-fat milk, Cocoa Metro is about half the fat and calories of ice cream: 240 calories for 1 cup. The milk comes from Vermont cows; it’s custom blended at a Massachusetts dairy and sold in handsome old-fashioned, returnable glass bottles. Drink chocolate and support local agriculture. Available at Bread & Chocolate, 108 Madison Ave., Newton, 617-243-0500; A. Russo & Sons, 560 Pleasant St., Watertown, 617-923-1500; and Formaggio Kitchen, 244 Huron Ave., Cambridge, 617-354-4750. www.cocoametro.com.
