With a base of habañero-infused tequila and arugula simple syrup, the Cocktail Club’s Spring Phoenix begins with a little spice. But the kicker is the ice: a whole orange habañero pepper frozen in the middle of a big cube. As the ice melts and the habañero’s oils seep into the drink, it’s transformed from a light, citrusy spritzer into a fiery cocktail that will leave beads of sweat on your brow.
