Partially freezing the ground beef before mixing in the spices helped prevent the meat from becoming compacted during mixing and shaping. But it's still important to use a light touch when handling the beef. The burgers can be cooked immediately after forming, but we found refrigerating them overnight let the flavors develop more. To pan-fry the burgers, heat 1 tablespoon grapeseed or other neutral oil in a large skillet over medium-high until smoking. Add the patties and cook until well browned, about 5 minutes; flip and continue to cook to desired doneness. This recipe can easily be doubled.
