Grass Fed Beef Celery Marrow Bones

These are bones, typically from the legs of the cow (shanks or femurs), that contain a rich, fatty tissue called marrow. This is a common term, though not a formal one, for marrow bones that are often used in recipes that include celery, or are prepared with celery as a flavor addition. Marrow bones are a popular ingredient for making bone broth, a nutrient-rich liquid that is a good source of collagen, minerals, and amino acids
