I am SFO Mom, and not SFO Chef:
This afternoon I very efficiently placed a piece of pork loin, some potatoes, sauerkraut, onions and seasonings into my Nesco roaster and left Big Daddy AND Big Brother with instructions to plug it in and turn it on in half an hour. I even put the meat thermometer into the roast.
Then I left to attend a choir rehearsal for Christmas.
When I returned, I checked the roast, which smelled delicious. The thermometer read 170 so I figured I'd better get it out of there NOW, as it was probably overcooked already.
I cut into the meat and found it still WAY pink inside. Then I noticed that the face of my thermometer looked a little, um, melted....yeah....I cooked an instant-read thermometer for 1 1/2 hours at 325. You know that surrealist painting of the melting watch? I almost had one of my very own.
The microwave finished cooking the pork for us, but I stuck to the potatoes and kraut.
