I learned this Working in the kitchen of a Fancy Restaurant in college. It works pretty well and I still use it today. Just remember that meat continues cooking for a little bit after you take it off the heat. Also this method is pretty useless with very thin cuts.
I have been doing this test wrong for years!!!!!!!! Don't wanna explain what part I was a pokin, but let's just say that these pictures and descriptions are great. Tahnks Trickbear.
This is the first pornsite I've found in years that I'd actually advertise to swarmers. When you first load it up, it looks just like every crappy scam site out there, except that it's real. It's huge, it's updated constantly, there's no spam, no popups, and no bullshit -- and it's completely free. When you sign up through that link above and respond to the confirmation email, I make a bit of loose change.
See what other swarmers have to say about it. People love this place, so I feel fine about sending you there and am confident you will enjoy boners.
