As David Wondrich says in Esquire Drinks, "Cocktails should not remind you of childhood; therein lies problems." Friends coming over for a party? Sure, make a pitcher of Margaritas. Just remember to leave the blender out of it.
3 parts silver Tequila
2 parts Cointreau
1 part lime juice
For a pitcher of Margaritas, stir all ingredients with ice to chill and dilute.
Strain out ice and store mix in the fridge until time to serve.
Crush ice in a Lewis Bag, cotton napkin or bar towel.
Pour Margarita mix over crushed ice in individual glasses to serve.
