House-made bone broth is coming to The Gruff, the popular restaurant near Covington's riverfront. It's offering free samples on Friday, March 2 and Saturday, March 3. Described as a "deep, flavorful broth", it's made with grass-fed bones or free-range chicken bones. The Gruff Bone Broth is available in pints for $8 or as a single serving size for $4.50. The Gruff sourced fresh ingredients and formulated a slow-simmered broth enhanced with herbs, turmeric, and/or ginger and can be enjoyed on its own.
