If you don't have a food processor (or mortar and pestle), try finely mincing the garlic and rosemary with a bit of coarse salt and mixing in softened butter with a fork. Add some olive oil if you like and heat gently - it's like bagna cauda. Drizzle on baby arugula with a smushed hard boiled egg and some crusty bread ... and prepare to feel the magic. Give anchovies a chance!
