How do you prepare the perfect burger patty?

Amazing ideas on burgers,,,I see some here I want to try as I have always put the ground beef in a big mixing bowl,,,add A-1 sauce with all of the spices and seasonings I can find in the cupboards,,,add one egg and then make burgers being careful not to pound or form the burgers into a pancake,,cook and burp some meaty goodness afterwards.
