What kind of cows make your liquor? This is an important question for the makers of Bailey's Irish Cream. Nearly 40,000 top-bred Irish dairy cows contribute cream to make the world's most popular liqueur. It's blended with pure Irish whiskey and a proprietary cocoa extract to make one of the best-selling alcoholic beverages on the planet. What can you mix it with? Nothing and practically anything. All by itself, perhaps on the rocks, it makes a smooth sipper. It's very friendly with coffee, hot cocoa and other liqueurs. Amaretto, peppermint schnapps, cinnamon liqueur or whiskey all get along nicely with Bailey's in a hot drink. Because of its weight and viscosity, Bailey's performs well with layered drinks. Building a multilayer shot takes some practice and touch, but it's an old-school skill that will wow your guests. Consider the classic B-52 coffee with Kahlua and Grand Marnier. While nice on the rocks or with coffee, the B-52 was originally intended to be a layered shot.
