How to Make It
Combine chicken leg quarters, 5 cups water, cumin, garlic, and 1 tablespoon salt in a large saucepan. Bring to a boil over high. Reduce heat to low; cover and gently simmer 25 minutes.
Stir in carrots, potatoes, onion, celery, barley, stewed tomatoes, diced tomatoes and green chiles, and jalapeños. Increase heat to medium, and bring to a simmer. Reduce heat to low; cover and gently simmer, stirring occasionally, until vegetables and barley are tender and chicken is falling off the bone, about 40 minutes. Remove chicken meat from bones; discard bones. Stir chicken and remaining 1/2 teaspoon salt into soup. Add salt to taste.
