My favorite way to use rosemary is to stuff it into the carcass of a whole chicken before roasting it. You could also stick it under the skin or just sticking up from the legs and wings. It's nice to stuff a chicken with fresh herbs like this and also some onion and lemon wedges. Simplyrecipes.com has some great recipes that utilize fresh herbs. You can go to their website and and type 'fresh rosemary' into their search box at the top right corner of the page and all their recipes will come up.
Fresh rosemary is also very nice with potatoes. You cut up some potatoes and toss them with olive oil. Add some fresh garlic you chop or mince and then seal it all up in some foil with the sprigs of rosemary and put it in the oven on about 350 for about an hour and that's yummy, too.
I find that when using the fresh sprigs I keep them whole. When using dried rosemary I use a mortal and pestle to grind them up more finely and find this is more 'user and eater friendly'.
It's pretty hard to find a recipe on the above website that isn't great. Have fun!
