CHURNING 



Rinse churn with hot water from 150 to 200 F., 

 revolving it from five to ten times, being careful to 

 leave stopper out. Draw off water and rinse again 

 in the same manner with pure cold water at about 

 40 to 50 F., leaving stopper in during the last 

 rinsing. Draw off water and pour the ripened cream 

 in, filling churn about one-third full so as to allow 

 the greatest splash in churning. Add vegetable 

 coloring, the amount depending on the time of the 

 year and the market requirements. If cows are 

 receiving no grass and the market demands a high 

 color, an ounce or 30 c.c. color to each 50 pounds
