Beef
Hamburger, Inspired by Andy Warhol's Hamburger
For a classic hamburger like this, I like to use 20-percent-fat beef. Grass-fed is great, but it just doesn’t yield that retro burger taste. Also, you must use one of those super thin, sesame seed-studded potato buns to get the proper experience. Don’t ask what’s in them, just bite and rejoice.
