One quart (32 ounces) of mix.
Eleven ounces of fresh-squeezed lime juice (fresh squeezed is key).
Eight ounces of simple syrup (combine equal parts sugar and water, bring to a boil and let cool).
Thirteen ounces of water.
1) Combine the lime juice, simple syrup.
2) Add 13 ounces of water.
*If the mix is too sweet, more lime juice can be added; if too tart, more simple syrup will reduce tartness.
*This makes about 9-10 margaritas.
