Update:
I took the tongue out an hour ago (from the pot) and put the stock/brine on the stove to simmer. It was 1:00 PM here. At 2 PM, I brought it to a rapid boil, added the meat and turned down to simmer.
I googled for 15-20 minutes on how long to cook a beef tongue and I must say that most folks are idiots. I got responses from 3 hours (no mention of size/weight) to '4 hours, add potatoes and boil another 4 hours'.
Seriously?
I'm thinking 1-1/2 hrs covered and an hour sans lid. 3 lb tongue at a slow roll fer an hour should finish it up nicely.
Some folks shouldn't talk of cooking.
BTW, the smell is... nice.
Whipped up a batch of coleslaw and biscuits. Wild mushroom gravy as a topper. And rice.
The wait begins.
