Local publicist Dana Zemack is obsessed with chocolate, and we’re reaping the benefits. Zemack, who leads tastings and workshops, and blogs about her chocolate passion at www.thetastyshow.com, has created The Tasty Show Chocolate Tasting Kit for Two ($39), available at Grand (374 Somerville Avenue, Somerville, 617.623.2429) and on her Web site. Each super-cute kit contains a selection of mini gourmet chocolate bars — two each of 12 different types — plus a tasting board, rating cards, and notes on tasting and what to look for in each sample. These are no kiddie-birthday-party treats, either: paired with adult beverages (Zemack suggests a fullbodied red wine or dark beer), the tasting makes for an excellent stay-at-home date night or gossipy evening with friends.
