Can I make hamburger patties the night before?

Chef's answer
Once the patties are prepped, "first things first -- season it," Ramsay said. "Try and get this done the day before," the chef said of seasoning raw patties. "If you get this done the day before, set them in the fridge so they stay nice and firm -- that way they don't fall apart on the grill.

    Place the meat in your pan and smash it flat. Press it down very firmly with a spatula. Make each patty as flat as you can. As long as it looks flat, it will cook evenly without ballooning up in the center. This won't work as well on a grill grate since the meat will get pushed straight through its openings.
    Add 1 egg yolk per pound of hamburger. It won't add appreciably to the fat content and will bind the meat beautifully. The other thing you can do is add canned, drained, crushed black beans or chickpeas to the hamburger. The starch from the beans will bind the meat together and add an interesting taste.
