"This is one of my favorite recipes that will be featured at my new restaurant in Phoenix, Arizona— 333. I love bone marrow and have been excited to see it grow in popularity over the past 10 years. What was once used almost solely for broth and even dog treats have now been discovered for the delicious treat that it is. I could go on and on about the history of bone marrow and the benefits for your health, but I think it's better we just cook it." -Chef Shaun O'Neale Before your start: Note that this recipe takes a full day of prep work before it's time to start grilling. You up for the challenge, pitmaster?
