For this recipe, you need a 52-ounce pitcher.
In a 52-ounce pitcher, add the lime juice, then the Cointreau.
Adjust the sweetness with a little agave syrup (2 parts agave nectar, 1 part water) or simple syrup (1 part sugar, 1 part water).
Add the tequila and taste.
The mixture should still be intense because you haven't added any ice yet.
To serve, pour 3 oz of the mixture into a shaker with ice and shake.
Srain into a stemmed Margarita glass with a half-salted rim or a rocks glass filled with fresh ice.
Garnish with a thin lime wheel.
If you have a large shaker or a gallon jar with a screw-top, you can shake a whole bunch of drinks at the same time.
