Yolk Quality
Outline Slightly Defined - A yolk outline that is indistinctly indicated
and appears to blend into the surrounding white as the egg is
twirled.(AA Quality).

Outline Fairly Well Defined - A yolk outline that is discernible but not
clearly outlined as the egg is twirled.(A Quality).


White Quality
Firm - A white that is sufficiently thick or viscous to prevent the yolk
outline from being more than slightly defined or indistinctly indicated
when the egg is twirled. (AA Quality).

Reasonably Firm - A white that is somewhat less thick or viscous than a
firm white. A reasonably firm white permits the yolk to approach the
shell more closely, which results in a fairly well defined yolk outline
when the egg is twirled.(A Quality).
