My dad was the best at well done roasts. If there was any moisture left in the meat it just wasn't done enough. He had this dial thermometer and would always make sure to check the meat for doneness. Fast forward about 25 years, I became the proud owner of my dad's grill thermometer. I put it in the drawer with my thermometers. Next time I grilled, I grabbed a thermometer from the drawer to check the meat for doneness. Amazingribs.com always recommends using a thermometer to check for doneness so even though I've been grilling for 30 years and have a pretty good idea what finished roast or chicken looks like, thought I would check with a thermometer. When the meat looked ready, I checked with this thermometer and to my surprise, it read 20 degrees under cooked. So.....I left it on the grill for another 20 degrees of cook time. Low and behold the finished product was reminiscent of one of my dad's grilled roasts!
The thermometer I used was my dad's. When I checked it for accuracy, it was a full 20 degrees out of calibration (for years and years I'm sure.) :confused2:
