Is a hamburger just good meat and seasonings? Can you add eggs, ketchup, mustard, bread crumbs and still call it a hamburger? The best homemade hamburger I ever had was at a party, and I think all those things were in the meat, and grilled over coals. But people have said that one of these things in not like the other. I say, one of these things is BETTER than the other. And still, a hamburger.
