If you don't own one, you should.
I'm often asked how to tell when a steak is done, as if there is a spell or incantation I might recite.
The truest, albeit smart-ass, answer is to take its temperature. It's the secret to knowing when your steak, or anything your cooking, is ready.
What you need to know is that they aren't always calibrated. To calibrate it, fill a cup with ice water and stir it well with your thermometer. It should read 32˚F. If it doesn't, there is a nut/bolt behind the face. Rotate it the appropriate direction until the needle points to 32˚F.
