Mix juices and sugar together and stir to dissolve. Add tequila and orange liqueur, stir and refrigerate; or serve immediately over crushed ice in salt-rimmed glasses.

1 part = 1/4 cup if you're making 4 margaritas (standard size for our group).

Freshly squeezed juice makes the best margaritas! Use Cazadores reposado tequila or better. Use Cointreau or Grand Marnier. Superfine sugar + water if you don't have sugar syrup made up.
