12oztequila(Go for a brand like Tequila512, Republic Tequila, or Z Tequila to go Texas local)
1/2cupTriple Sec
Ice
Lime and coarse salt, for garnish
Instructions
Fill a blender about half way with ice. Pour in the tequila, Triple Sec, and lime juice concentrate, then fill the blender the rest of the way with ice.
Pulse until smooth, then pour into glasses with salted rims and garnish with lime.
Notes
Generally, using fresh lime juice would be a good idea. But since the ice dilutes and masks the lime flavor, we need something a with little stronger flavor.
