Give kitchen grilling of steak a shot sometime soon..
Grilling Tip: Check steak doneness by pressing a steak in the center. Then use your thumb, fingers, and the varying firmness of the base of your thumb as your guide.
Determine the doneness of a steak: You touch your thumb to your index, middle, ring, and pinky fingers, and the further you reach, the harder your muscle becomes. Apparently this should match up relatively well with rare, medium rare, medium, and well done steaks as you work your way from index to pinky.
