Interestingly, I made a pork loin in a dutch oven Saturday. Pretty much the same technique discussed above, with one variation. After rinsing the brined pork loin and patting it dry, I cut twelve slits, about an inch wide and an inch and a half deep, in the skin/fatty side of the loin. The slits were three apart and four down, evenly spaced. I had taken 1/2 tsp salt, 1/2 tsp cracked pepper, and 1 1/2 tsp dried thyme and mixed them together. I also took a couple of garlic cloves and sliced them lengthwise into twelve thin slices. I put about 1/8 tsp of the salt/pepper/thyme mixture into each slit, and one of the garlic slivers. I then took twelve bay leaves and put one of them into each slit as far as I could. About half of each bay leaf protruded. The remaining salt/pepper/thyme mixture was sprinkled over the top of the loin.
I took a big white onion and sliced it thickly - about five slices. I put these in the bottom of the dutch over, and put the pork loin on top of them. I then poured a full bottle of Madeira into the pot. I placed a piece of parchment paper directly on top of the loin, and then covered the dutch oven.
This went into a 325 degree oven for 4 1/2 - 5 hours. At the end of this time, I removed the loin to a warm platter, removed the bay leaves, tented it with foil and let it rest. I strained the cooking liquid through a fine sieve, smushing the onion against the sieve with a wooden spoon to get as much juices as possible out of them.
In a large skillet I sautéed in two tablespoons butter chanterelle, shitake, and oyster mushrooms that had been sliced into pieces about 1/3 inch wide. Cooked them about five minutes before I added the strained cooking liquid, and continued to cook the mushrooms until the liquid had been reduced by half. At this point I added a half pint of cream, and cooked until warm.
The pork absolutely fell off the bone! We served it with sautéed spinach and creamy grits, with the mushroom sauce spooned over the pork and grits.
Heaven on a plate! Sorry I’m so late to the thread.
eta re:brining. Easy. Dissolve kosher salt in cold water at the rate of one cup of salt to one quart of water. Do not use regular table salt - the brine will be too salty if you do. Make enough brine to cover the pork after you’ve put in in a container. Pour the brine over it, cover the container, and store in a cool place for 12-24 hours.
