Don’t cut into it right away! That’s a rookie mistake. All the juices run out and you make a puddle of sadness. Let it rest for 10 minutes.
Now, make a small incision. Look at the juice that pools on the cutting board. Clear or slightly pink juice is perfect. Red juice means it’s still raw. No juice at all means you’ve killed it.
It’s like reading tea leaves, but tastier. You are a lamb soothsayer.
