It's a self-explanatory concept — a shot of well tequila, chased with a half-shot of leftover pickle juice. It may sound gross or weird, but the briny, sour pickle juice completely cuts the burn of the tequila (and masks some of the not so high-end flavor). If you're still not sold, think of it this way — you'd typically pair a tequila shot with lime and salt, unless you're trying to be European and use orange and cinnamon. The lime is sour; so is pickle juice. The salt is, well, salty; so is pickle juice. More commonly, you'll find picklebacks, which are pickle juice and whiskey and very hip in New York City right now, but we love Palo Verde Lounge for putting a Southwestern twist on this trend. Whether or not they knew it was a trend when they came up with it is anyone's guess, but the low-brow shot served at this dive in Tempe is still the best, regardless.
