Heat a heavy pot or dutch oven over medium heat. Add oil
Add beef, season with salt and brown meat on all sides
Once meat is brown, add carrots, celery, onion and garlic. Cook for 3-5 minutes, scraping up any brown bits from the bottom of the pot
Add water and bouillon and bay leaf ; bring to a boil
Once soup boils, reduce to a simmer and cover. Simmer about 2 hours
Add the barley, adjust salt and pepper
Simmer 35-40 minutes more. Remove bay leaf.
I like to measure or weigh out my soup and divide by 8. Each time I make it there is a slightly different amount due to evaporation of the water, depending on how fast or hard it boils.
