a Broth from sample No. 1780. 



Cooking Experiment No. 155. 



The second piece of lean beef round (sample No. 1781), cut about 5 

 inches thick and 4 inches across, was cooked as a pot roast. A small 

 quantity of beef fat (9 grams) was heated in a flat-bottomed kettle until 

 "smoking" hot, the meat added, and well browned on all sides. A 

 small quantity of water was added from time to time and the cooking 

 continued for three hours, the pot being kept closel}" covered. The 

 cooked meat was well done and medium dry.
