I can't for the life of me understand why people use store-bought margarita mix, especially since a perfect margarita is so simple to make without it. You only need three ingredients:
Just put some ice in a shaker, add 1.5oz tequila, 1.5oz triple sec, and the juice of 1 whole lime. Shake it until it's ice cold, and strain in to a martini glass. Done! Ahhhh… sip the perfection.
Note: if you want to make a Waborita, just add a splash of Blue Curacao to the martini glass.
