This butter is nothing more than a stick of butter seasoned with aromatics. You can store it in the freezer or slice off a bit as you need it. Great on steak, fish, shrimp, chicken, potatoes, or other veggies. You can also use this as a base and add different chili powders like Aleppo or pimenton d'espelette.
