Coconut Margarita

Pour coconut water into a small, shallow plastic container or ice-cube tray and freeze until solid, 4 to 5 hours.

Place the frozen coconut water in a blender; add tequila, lime juice, triple sec, cream of coconut, ice and salt. Process until smooth, about 30 seconds. Pour into 2 frozen rocks glasses and garnish with lime wedges, if desired.
