A spicy but refreshing margarita from the Fairmont Mayakoba in Riviera Maya, Mexico, in honor of the Mayan apocalypse.
Rub rim of a chilled glass with a piece of lime. Dip the rim of the glass in a saucer of salt and chili powder until it is evenly coated. Mix all ingredients in a shaker or blender with ice. Pour into the glass and garnish with a thick slice of cucumber.
