I use a recipe from the Zuni Cafe in San Francisco.
I buy chuck, cube it up and salt it with kosher salt overnight. I grind it up in the food processor, form the patties add pepper.
If Im only making a few I fry them in a cast iron pan which gives a great crust otherwise I grill them and top with a good Gruyere cheese.
Serve on warm herbed focaccia with garlic mayo and red onions
Yum!
Salting a chicken the night before you roast makes it perfect too!
