Guava Margaritas

Stir together lime juice, tequila, Grand Marnier, and guava puree in a large pitcher; stir to combine. Refrigerate until chilled.

Just before serving, rub a cut lime around the rim of each glass. Fill a saucer with salt, and dip each glass, upside down, into the salt. Pour margaritas into glasses, garnish with lime wedges, and serve immediately.
