SC - Re: egg straining

[Mbatmantis at aol.com]

USDA egg quality is determined by :
   the shell (is it clean, unbroken and of normal shape), 
   Air cell (generally the smaller the air cell in the egg, the fresher the 
egg-have you            
                  ever heard that you can test the freshness of an egg by 
floating it in water? 
                But since the air cell of an egg may be effected by the 
humidity that the egg is     
                    stored in, this isn't an absolute way to judge the age of 
an egg)
    the white (the are judged on the clarity and firmness)
    the yolk (looking for  a yolk that is of uniform shape, only slightly 
defined from the    
                   white -indicator of whites quality- and centered in the 
shell)
   The inside is seen by candling- the same process used to determine 
fertilization.

   I was wrong about the size determining the grade of the egg; that is it's 
own separate category and is determined by weight.
