Simple salt, pepper, & garlic seasoning hours beforehand. Lots of each
Browned in the Dutch oven. With mine, I heat it over low for a while to preheat, then turn the temp up barely to med-low to brown. Longer browning time, but less scorching. Remove the meat. Sautee 1/2 sliced onion, 5 sliced garlic cloves, then stir around a can of tomato paste. Once it looks like the tomato paste will start to stick and scorch in the pan, deglaze with a cup of red wine (I prefer a Cabernet for this) and cook down about 5 mins. Put the meat back in the pan, add stock and mix all the stuff around. The liquid should come up about 3/4 of the way on the meat (not the whole bone) just the meat. Bring it all to a boil, cover, then put in a 225° oven.
I closed the oven door at 10:00 that night, and it went all night until Mrs. TAFKAP woke up at 0430. She turned the oven off and left it.
When I got home from work later that day, she had just shredded all the meat and started bringing the pot back to a boil. When it did, turn off all the heat, put the meat back in , and stir. We served it over garlic smashed potatoes. But rice, polenta, or even pasta would work great too.
