What each ingredient does
- Beef bone
- Gives the broth its meaty body and savory depth as it simmers.
- Tomatoes
- Supply the main flavor, acidity, and body of the soup as they cook down.
The step that matters
Boil until the soup reduces to 2 quarts. Simmering concentrates the flavor of the broth and tomatoes. Stopping too early leaves the soup thin and watery, while boiling too hard for too long can over-reduce it and make the flavors harsh.
