Preheat oven to 300º. Trim any excess fat from the ribs.
In a large dutch oven, put 1 can of sauerkraut, with juices, into the pot and spread along the bottom. Place one layer of pork ribs on top of sauerkraut. Season with salt and pepper. Add another can of sauerkraut over the ribs. Sprinkle generously with brown sugar. Repeat with another layer of pork ribs, salt and pepper, another can of sauerkraut. Top with brown sugar. (So I did two layers of pork and 3 cans of kraut. You may want or need another can of sauerkraut. Just adjust to your amount and size of ribs and pot.)
Add water to the side of the ribs, enough so liquid comes ¾ of the way up the pork and kraut, I added about ½ can of water. Cover pot with lid.
Place in middle of oven and braise for 2½ - 3 hours, until pork is very tender when pierced. You can remove the lid the last 15 - 30 minutes if you want the top more brown.
Remove from oven and skim any fat from the top. Serve with mashed potatoes, and maybe apple sauce (not baked beans!).
