Marrow-rich bones from our 100% Grass Fed, Grass finished cattle, raised on organically-managed pasture. Simmer these with a splash of vinegar, half an onion, a stalk of celery and a bay leaf for a rich, nourishing stock. Want even more flavor? Roast them in the oven until they are deeply browned before putting them into your stock pot, slow cooker or pressure cooker! Sip the broth as a gut healthy, nutrient rich tonic or use it for soups, stews and sauces.
