I pride myself on my margs when I'm making 'em for my wife and I. I use tequilla (duh!), Contrieu, fresh lime juice, and some Bone Daddy's sweet & sour. But I got a bar-b-que coming up and don't have the inclination to squeeze all those limes, plus I want to have them already made and sitting in a punch bowl while I cook. Is there a recipe that would work for a larger group? Maybe substituting frozen limeade for the fresh juice? TIA.
