Zuni Cafe Hamburgers

When we went to Zuni Cafe last month, Lisa ordered a hamburger. It came on focaccia bread with arugula, pickled onions and aioli. The secret to the burger is to salt strips of chuck and leave them in the fridge for 24 hours prior to grinding. I made the focaccia from Cooks Illustrated's The New Best Recipe cookbook. The "recipe" for the Zuni Burger is in The Zuni Cafe Cookbook
