The reigning king of cocktails, the Negroni, is made for boozy marmalade. This version, which puts both oranges and grapefruit to work, is the definition of a classic marmalade—until you add Campari to the mix. Not only does the Italian aperitif lend a beautiful crimson color to the spread, it also gives it a subtly herbaceous twang. Spread a little over brie and crackers for an edible accompaniment to the real deal cocktail.
Yield: 25 ounces of marmalade
