It only takes 4 ingredients (plus an empty ice cream pail) to make this easy Margarita Slush, and it's great for backyard barbecues, pool parties, and summer nights.
In an empty one-gallon ice cream pail, combine limeade concentrate, tequila, triple sec, and 2 liter bottle of soda. Place in the freezer and chill at least 8 hours, overnight, or up to a month in advance.
Remove from freezer 1-2 hours before serving. As the slush melts, it will become easier to scrape and serve.
To serve, add 1 cup slush to a glass (rim the glass with coarse salt if desired, see note 3). Top with additional soda and garnish with a lime slice or wedge.

Notes
Tequila: Tequila blanco is lighter in body and perfect for making cocktails like this one. Tequila reposado (which means “rested” and is aged in oak for at least 2 months) is ideal for sipping.
Triple sec: Or any orange-flavored liqueur such as Cointreau or Grand Marnier.
Salted rim: In a shallow dish as wide as your serving glass, add Margarita salt (or kosher salt) to 1/4-inch deep. Run a lime wedge around the top of each glass, then dip the top of the glass upside-down into the salt and turn to coat.
Yield: This recipe makes a batch of 12 cocktails.
Glassware: A Margarita glass is the classic choice, but I love how approachable a lowball glass is for happy hour.
