Chevy's Frozen Margarita
About 1 ½ cups crushed ice
4 ounces Fresh Sweet and Sour Mix
1 1/4 ounces tequila
1/2 ounce Triple Sec
1 thin lime slice
Sweet and Sour Mix: Combine 1 ¼ cups freshly squeezed lime juice, 2/3 cups freshly squeezed lemon juice, and 2/3 cups sugar in a blender until the sugar dissolves.
Frozen Margarita: Salt the rim of a 12-ounce frosted mug. Combine the tequila, Triple Sec, sweet and sour mix, and ice in a blender. Blend just until slushy and well mixed. Pour the margarita into the mug, garnish with the lime slice, and serve.
