A broccoli recipe for those who thought they hated broccoli. Brocconlini is sweeter and milder tasting than mature broccoli. Found this jewel of a recipe in my March 2003 Better Homes and Garden magazine. Fresh asparagus, pea pods or romanesco would make excellent substitutes for the broccolini. Mascarpone is available at Trader Joe's and well-stocked grocery stores.
