Ingredients
1 lime, halved
Kosher salt
1/2 cup freshly squeezed lime juice (5 limes)
2 tablespoons freshly squeezed lemon juice (1 lemon)
1 cup Triple Sec
3 cups ice
1 cup white tequila

Method - The Procedure
If you like margaritas served in a glass with salt, rub the outside rims of six glasses with a cut lime and dip each glass lightly into a plate of kosher salt.

Combine the lime juice, lemon juice, Triple Sec, and ice in a blender and puree until completely blended. Add the tequila and puree for 2 seconds more. Serve over ice.

If you prefer frozen margaritas, halve each of the ingredients, double the ice, and blend in two batches. Serve with a cut lime.
