Chef Sue Torres, owner of Suenos restaurant, joins Martha in the kitchen to make 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.
