How should butter be packed into tubs? 



The wooden butter ladles should first be cooled 

 with cold water to prevent butter sticking to them. 

 The butter should then be firmly packed in small 

 amounts at a time and using plenty of muscle in the 

 work. The circumference should receive more 

 packing than the center, because when the butter 

 is turned out of the tub for cutting, it is very 

 necessary that the surface be free from all me- 

 chanical holes. Solid packing is of considerable 

 aid in preventing the entrance of mold. The tubs 

 should be filled to the top with butter. In filling, 

 the butter should be heaped up and then leveled 

 off by drawing a small wire or string across the 

 surface. The extra butter can then be rolled off 

 and the surface is left smooth and level. 



The paper linings should be so fitted that they 

 overlap about i inch on the top surface. Then on 

 top a cotton circle should be placed and over the 

 circle a small amount of dampened salt is sprinkled.
