If we want to drink tequila, we're going to drink it straight. But lately, we've been thirsting for that most adult of slurpies: a frozen margarita. Popular in other parts of the country, they're a rarity in Colorado (probably because the heated stares of margarita purists are enough to melt them into syrup) but a specialty at Hacienda Colorado, the "Mountain Mex" chain founded by Tim Schmidt. He's even the namesake of one of his homegrown chain's frozen margs, the Timmer, which has a Grand Marnier floater. But we prefer Hacienda Colorado's frozen house marg, made with nothing more than Margaritaville Gold Tequila and fresh-squeezed lime juice. Cool!
