Savory Jewish comfort food.A lot of effort went into testing this recipe. The traditional "stretch" or knish dough is one many bakeries, Jewish restaurants and homes use, but I found it a mite dry and crisp. Still other knish recipes and fanatics rely on commercial puff pastry. The texture is fine, but it lacks flavor. This "mock puff dough" for knishes is a little off the beaten path but it makes for outstanding knishes - light, buttery, melt-in-your-mouth morsels that are embarrassingly easy to make by the truckload. They freeze without problem in case unexpected company drops by.
