“Note: When shopping for ground beef, look for a fat content of at least 20 percent (80/20 beef). Plain old ground chuck will do. For a superior burger, combine 50 percent ground sirloin with 25 percent ground fatty short rib and 25 percent ground brisket. To clarify butter, place it in a small microwave-safe container and microwave in 15-second increments until fully melted. Skim off the white scum from the top surface with a spoon and discard. Carefully pour off and reserve the yellow butterfat, discarding the milky white liquid at the bottom.”
