Phones can die. Batteries fail. Here’s a backup: the hand test. Make a “peace sign” with your hand. Feel the fleshy part below your thumb.
Relax your hand. That softness? That’s raw lamb.
Now touch your thumb to your index finger. The fleshy bit firms up. That’s rare. Thumb to middle finger? Medium-rare. Pinky to thumb? Well-done (or a dried-out shoe).
This test is weirdly accurate. And it impresses everyone at the table. Become a finger oracle.
