Mexican Sour

Every so often, you find cocktails that wake up your taste buds in the best way possible, and the Mexican Sour is exactly that kind of drink. The first time I made it, I was curious how grapefruit and chili would come together, but after one sip, it made perfect sense. It had that bright citrus kick, followed by a gentle heat that kept things interesting.

This cocktail takes the familiar idea of a sour and gives it a bold twist with tequila and a hint of spice. You still get that smooth balance of sweet and tart, but now there is an extra layer that makes it stand out. I love this because it feels refreshing at first, then slowly builds with a subtle warmth that keeps you coming back for another sip. Inspired by cocktails.and.craftery.
