I mentioned this method of determining how cooked meat is without cutting into it the other day. I learned about it ages ago, and only just remembered to share it when I found it mentioned on LifeHacker.
By touching your thumb to each of your fingers, and then pressing on your thumb muscle as it changes firmness, you’ll get an idea of how your steak should feel, moving from rare to well done as your thumb muscle moves from your index to your pinky finger.
