To gauge the doneness of meat, Raichlen uses the "Poke Test." Here's how it works: Make the OK sign with your thumb and index finger. Now, touch the pad of flesh at the base of your thumb. The flesh should feel soft and squishy; this is what rare meat feels like, according to Raichlen. Switch to your middle finger, and the pad feels a bit firmer--that's medium-rare. Your ring finger is medium. And with your pinky, it's well-done.
