To form the patties, divide ground beef into four equal portion and shape each into a circle about 4 inches wide. Lightly season with salt and pepper or seasoning of your choice.
Place the patties in a freezer bag, and remove the air using the displacement method. Drop bag in the water bath for 1 hour.
Remove patties from bath and pat dry with paper towel. Re-season with salt and pepper. Turn grill on high and cook the patties for 1-2 minutes on each side.
