what kind of meat do u all use for your burgers??
i used to use ground sirloin with as little fat as i could find (i for some reason thought this was less risky in regards to mad cow disease, and chuncks of grizzle).
i have been *educated* that my precausions will not help in this area.
so, what kind of beef do u all buy, and what % of fat content do u find best?!?
