In the special May/June 2018 edition of “What’s New? Massachusetts,” we chat about designer donuts with Joshua Livsey, executive pastry chef from Harvest Restaurant in Cambridge and finalist on the Food Network’s “Holiday Baking Championship.” Livsey’s team has unleashed a donut pop-up at Harvest Restaurant on Sundays. We also talk about our favorite new donut shops in Massachusetts including Union Square Donuts in Somerville, the Donut Experiment in Provincetown and the Donut Factory in New Bedford
