Craig Claiborne's Ultimate Hamburger

I found this same recipe, minus the Tabasco sauce, somewhere on the web. It's really easy. Essentially you just sear, then cook some plain hamburger patties, then top with a pat of butter (I think it's a good idea to do this in the pan, so the butter can be soaked up when you toast the buns), and a little sauce made of (for each patty) 1/4tsp Worcestershire sauce, 1/8tsp Tabasco sauce, 1/2tbl lemon juice. Sprinkle on 1tbl chopped parsley. You might add a slice of onion. Extra yummy.
