Rosemary salt is a nice way to preserve the flavor of the fresh rosemary you may have growing in your yard. I'm growing rosemary in my backyard and in a large pots on the deck. Rosemary salt goes well with a lot of foods, especially roast pork and potatoes. Try sprinkling rosemary salt in olive oil and using it for dipping fresh bread.
All you need is 1/4 cup finely chopped fresh rosemary and 1 tablespoon of Kosher salt. Mix the rosemary and salt together in a bowl and put it in a clean glass jar. Cover and store at room temperature, away from direct light or heat, until the end of eternity.
