But doesn’t the temp keep rising after you pull it off the heat (and so shouldn’t you take it off below the target temp)?
Yes, it does, and I mentioned that. I take off the steak when the internal temp is 125, and it will carry to about 130 while resting, which is what I call rare. Likewise, remove at 130 and let it carry to 135 for medium rare, etc.
If you're one of those vampire types that like your steak bloody, take it off at 115, and it will carry to 120.
