Generously salt and pepper the beef. In a large stockpot, heat the oil over medium-high heat.

When it is very hot, add about ⅓ of the meat. Brown for about 1-2 minutes, then turn to brown the other side. Remove to a plate when it is browned on all sides.

Repeat with remaining meat in 2 more batches. (If you add it all at once it will steam the meat instead of browning it--not what you want.)

When all the meat is browned, add all the meat back to the pot with 10 cups of water. Add 3 healthy tablespoons beef stock concentrate.

Add the chopped celery, onions, and garlic. Bring to a boil, then turn the heat to medium-low. Simmer for about 2 hours with the lid on.

When the meat is tender and you can break it apart easily with a wooden spoon, add the shredded potato and carrots. Bring to a boil, then continue to simmer on low for another 30-45 minutes, or until the carrots are tender.

Add 1 cup of barley. Bring to a boil, then reduce to low. Cook for another half hour, or until barley is tender and the soup tastes...like home.

In a large pan, brown the meat according to the instructions. Remove the browned meat to a large crockpot.

Add 2 cups of the water to the pan and bring to a boil. Stir up all the browned bits. Add this and the remaining 8 cups of water to the crock pot.

Add the beef base, celery, onions, and garlic to the slow cooker and stir.

Cook on low for about 6 hours. Add the potatoes and carrots and cook for another hour.

Add the barley and simmer for another hour or so, until it is tender.
