You’re not going to get a real margarita from a bottled or powdered mix any more than astronauts on the space station are going to get a real steak by adding water to the freeze-dried stuff NASA sends up there with them. And speaking of freezing… a frozen margarita is a delicious and refreshing summertime treat, but do you think you’re really going to taste the interplay between the tequila, lime juice, and triple sec when your tongue is half-numb with cold? If you want a Big Gulp, go to 7-Eleven. Get your ‘rita on the rocks, or even straight up, as long as it’s well-shaken with plenty of ice before it’s served. The secret to making a good margarita is simple: use quality tequila, fresh-squeezed lime juice, and follow the recipe until you’ve learned enough to be able to mess with it.
