Directions

1. Roll limes on counter to release juices. Cut limes in half and cut a slice off one half to save for rimming the glasses.
2. Squeeze juice from limes into blender, add mango, tequila and Cointreau. Blend until smooth, add ice and blend.
3. Taste to see if you need to add more sugar (it will depend on the sweetness of the mangos).
4. Combine the kosher salt and coarse sugar in a flat bottom bowl. Rub the rims of the glasses with save lime slice, spin the rims of the glasses in the salt and sugar mixture, fill glasses and enjoy.
