Being a minister's daughter, I used to love when the Bishop would come for dinner. Mom would make her special meals and this one I loved above all others... as do my kids today. The smell that envelopes the house when the pork is roasting brings back warm memories of my childhood!
Place pork roast in 13x9" roasting pan. Cut onion into wedges and tuck around roast in bottom of pan, and a few across the top. Sprinkle garlic powder, salt and pepper over roast. Bake @ 400 degrees for the first hour and then reduce heat to 350 degrees until done. (Note: You want the onions to caramelize so the juices are a nice dark brown when the roast is finished cooking. Adding 1/4 cup of water after the first hour helps attain this for you. These juices are for the sauerkraut & dumplings and the darker, the better!)
In a large mixing bowl, measure 4 cups of flour. Make a well in the center of the flour and break the 4 eggs into the well. Begin stirring the eggs and drawing the flour into the egg as you stir. Gradually add the 2 cups of water. Sometimes it doesn't need quite the 2 cups... Stop adding water then the dough is fairly firm but sticky.
Bring 4 quarts of water to a boil in large pot. Using a soup spoon, scoop spoonfuls of the batter into the boiling water. Reduce the heat a tad and boil for 10 minutes. Watch the pot... this will foam up and start to spill over if not watched!
Drain the dumplings and return them to the pot. Add the 2 cans of sauerkraut to the dumplings and simmer on low until the roast is ready to come out of the oven.
The last and most important step... put the pork drippings and cooked onion into the sauerkraut & dumplings. This adds amazing flavor and the sauerkraut is a nice golden brown.
We always have this with applesauce on the side. Makes it complete!
