Richard has been on the road without Jazmin! This week he comes to us from Williamsburg yet again to sit down with Wylie Dufresne of Du's Donuts. Wylie is one of America's leading proponents of molecular gastronomy and incorporates science into his cooking techniques. His donut shop that began as a pop-up is now a chain with its very own cookbook. The two talk about the novelty of cookbooks and the value of having an international collection. Wylie explains his love of flashlights and the true physical demands required for a donut chef.
