If you’ve ever been curious about cocktails–the history, science and stories behind everything from an Old Fashioned to a Sazerac–consider attending this month’s Masters of Social Gastronomy talk at Brooklyn Kitchen. Sarah Lohman of Four Pounds of Flour and Jonathan Soma of Brooklyn Brainery will be on hand to explain the ins and outs of one of America’s greatest inventions. Understanding the origins of some of your favorite alcoholic drinks isn’t necessary to enjoy them, but the class promises to be a lot of fun–you might even find out once and for all whether martinis are supposed to be shaken or stirred. The lecture is $5 and includes two free beer tickets, plus 10% off BK cookware. You can sign up here.
