Kapusniak: Polish Sauerkraut Soup
Kapusniak is a wholesome and filling Polish soup made from sauerkraut or fermented cabbage and potatoes. Eaten meatless during the season of Lent, the soup can include bacon and kielbasa at other times.
- 1 lbs of pork ribs
- 1/2 cup of smoked bacon, chopped in cubes without skin
- 1.5 cups of sauerkraut
- 5 bigger potatoes
- 1 small onion
- 2 medium carrots, grated on large meshes
- 2 bay leaves
- 3 grains of allspice berries
- 1/2 teaspoon of cumin
- 1/3 teaspoon of salt
- 1/4 teaspoon of pepper
- Pour five cups of water over the pork ribs. Add two bay leaves, three grains of allspice, and salt. Cover and cook for 1 hour.
- Remove the meat after it's cooked and put it in the bowl. Leave the bullion in the pot and add sauerkraut with the juice from it as well. It adds to the flavor.
- Cook it for about 30 minutes, until the sauerkraut is soft.
- Meanwhile, peel the potatoes and carrots. Chop everything into small cubes and cook for about 15 minutes in a separate pot. Set aside when cooked, still in the water.
- Place smoked bacon in a cold pan. Set the burner to medium power and wait until the bacon fat starts to melt and the bacon turns brown (about 10 minutes).
- Add the peeled and finely chopped onion and the peeled and grated carrots to the pan. Stir everything together and cook for 10 minutes.
- Put it all into the big pot already with the cabbage. Add half a teaspoon of cumin (which may be ground) and pepper. Cook it all together for 10 minutes, then add already boiled potatoes and carrots (along with the water). Enjoy!
- If you like your soup thicker you might make a thickener. You'd need to melt a spoon of butter on a small pan, then add a spoon of flour and mix it instantly. When the fat with flour starts to create foam, pour it all into the pot and bring to boil.
If you're using jarred sauerkraut instead of a fresh one cook for only 15-20 minutes instead of 30 min.
