This is a wonderful recipe for Margaritas on the Rocks by the pitcher-full! It is best to prepare the lime-lemon juice and zests mixture before hand to allow them to meld appropriately — Cooking time reflects refrigeration time. I discovered this in Cook’s Illustrated Magazine — just in time for summer! I have altered the ingredients to suit my personal taste. Enjoy!
Combine lime zest and juice, lemon zest and juice sugar, and salt in a large measuring cup; cover with plastic wrap and refrigerate (preferably overnight).
Divide 1 cup crushed ice between 4 to 6 margarita glasses.
Strain juice mixture into 1 quart pitcher or cocktail shaker.
Add Patron tequila, Triple Sec; stir or shake to combine thoroughly.
Pour over ice; serve immediately and enjoy : )
