ON A RECENT trip to the bar at Washington Ave.’s B&B Butchers for a nightcap of espresso martinis, the bartender suggested his guests try a carajillo instead. The Spanish cocktail is made of espresso and Licor 43, the latter of which is named for its 43 ingredients. And, while the exact recipe is guarded by the Spanish family that distills it, it is known to contain citrus and vanilla, the two most prominent flavors. Many of Houston’s hottest restaurants are putting their own twists on this cocktail that’s giving espresso martinis a run for their money!
