Most restaurants use a machine for making Margaritas and Daiquiris....it's a slushy/smooth liquid with all the additives and they just add the alcohol. It saves a lot of work/time with the machine. I don't like them that way. Back when I used to bartend, this bar I worked at had Margarita Monday and sold them cheap that night. When that machine would break down and we had to make them all by scratch with a blender it was a nightmare.
