Recipe from Barefoot Contessa
1 lime, halved
1/2 cup freshly squeezed lime juice (5 limes)
1/4 - 1/3 cup orange juice (not part of original recipe, this is my personal add in - fresh squeezed if you have it!)
1 cup Triple Sec
3 cups ice
1 cup white tequila (use the good stuff if you have it!)
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, orange 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.
