For this first time ever, I have successfully over-wintered Rosemary in a pot outdoors. I am thrilled to have fresh rosemary to cook with that I thought that I would share my favorite way to use it. Start with fresh rosemary that has been washed and dried off. Put some olive oil and fresh rosemary in a skillet, then warm over medium heat. Once the rosemary has lost its bright green color, remove from pan. Use flavored olive oil right away to flavor eggs, potatoes, asparagus or mushrooms.
