To make a bargain frozen margarita, puree five cups of ice cubes in a blender. Add 3/4 cup of tequila, 2/3 cup of fresh lime juice, and 1/2 cup simple syrup and blend until incorporated. Place 1/3 cup of coarse salt into a bowl. Using a lime, wet the rims of four glasses. Dip the moist rims into the salt. Divide the contents of the blender evenly between the glasses. Serve with a lime wedge garnish.
This recipe yields four servings. In order to prepare frozen margaritas for a larger crowd, multiply the ingredient amounts accordingly.
The most expensive ingredient in a margarita is the tequila. As of 2015, prices range from around $10 to greater than $50 for quantities of 750 milliliters to 1 liter. A taste test by Serious Eats found that the tequila's price point did not accurately predict the quality of the margarita. Tequilas with lower prices, such as Suaza and Jose Cuervo, which retail for around $10 and $20 respectively, made inferior margaritas. Tequilas like Casa Noble Crystal, which has a midrange price of around $30, produced delicious margaritas, whereas Patron, the most expensive tequila at around $55, yielded a less noteworthy cocktail.
The deciding factor for quality margarita tequila is the type of sugar used to make the tequila. On the whole, reviewers prefer margaritas made with 100 percent agave tequilas. These alcohols contain only agave syrup as the sugar source. Less popular were mixtos, a type of tequila that uses non-agave sugars during production. Mixtos margaritas often have an oily texture and bland flavor.
