In recent years, only one new bottle of booze has earned a spot on the shelf behind my bar: Aperol, an orange-red Italian aperitif. Get used to this name…it is Italy’s hot new cocktail mixer. I had an “Aperol Spritz” in Modena about two years ago, and I was hooked instantly; it has become de rigueur at the start of my Italian dinner parties. The comparison to Campari makes the case. I love Campari, but many of my co-Americans find it too bitter.
