Correct way to bake turkey demonstrated by Uncle Sam's expert cooks. Washington, D.C., Dec. 4. Note to housewives: your turkey- baking troubles will be over and the bird you serve for dinner this yuletide will be tender, juicy and flavorsome if you follow the method used by the expert cooks at the Bureau of Economics, U.S. Department of Agriculture. Continual testing and experimenting with various recipes has taught Uncle Sam's cooks that many a prize bird has become a "ham" when improperly prepared. The best recipe - so far discovered by the Bureau of Economics - is demonstrated in the following set of pictures, made under the supervision of Miss Lucy Alexander, Chief Cooking Specialist. Miss Alexander, a graduate of Vassar and the University of Illinois, has been on her present job for eleven years. Mrs. Jessie Lamb, Assistant Cook, is stuffing the turkey under the watchful eye of Miss Lucy Alexander. The turkeys on the table will go into the ovens at regular intervals, and be tasted and judged by a group of experts who are determining which diet and feeding program will produce the best flavored meat.
