For one drink:
oz of tequila
oz of your fresh sour mix
cups of ice, depending on how thick and how strong you want the drinks to be. Blend on medium speed for 10-15 seconds until smooth.
Serve in a chilled glass with a salted rim and a wedge of lime.
Here's how: start out with fresh sour mix, which is a 2:1 ratio of fresh squeezed citrus juice to simple syrup. For example 2 oz lime juice and 1 oz. simple syrup. Simple syrup is just equal parts water and sugar (just stir sugar with warm water until the granules have dissolved. With either recipe, I would recommend adding a splash of Triple Sec or Orange juice to give it a little extra sweetness and a kick of flavor. Enjoy!
