Step 1

In a large freezer-safe bowl, combine limeade, pink lemonade, lime juice, club soda + lemon-lime soda. Mix in tequila and 3 oz of Cointreau, cover and freeze.

Step 2

Stir it every few hours so it freezes evenly. Ideally, allow it to freeze for at least 24 hours.

Step 3

If you like a salted rim: Pour some coarse salt onto a plate or shallow bowl large enough to fit the opening of your glass. Moisten the rim of a glass with lime juice/wedge. Dip the rim in salt.

Step 4

Upon serving, scoop 8 oz of the frozen mix into a glass and float 1/2 oz of Cointreau on top. Garnish with a slice or wedge of lime.
