We like to drink a mug of it, just like you would coffee or tea. In fact, a warming up a cup of broth and adding a pinch of salt to taste is a great way to start your morning—try drinking 8 ounces a day, every day. Of course, you can use it in recipes wherever it calls for broth or stock, or turn it into a base for your favorite soup.
People definitely add spices to the bone broth all of the time! I have heard people adding garlic powder, cayenne, ginger, and coconut aminos. One customer said she uses it to make rice instead of water. Also, you could try brewing it with fennel or another savory tea.
