Today, it is the Paloma. The fruity, fizzy, tequila-based Paloma has become my favorite drink to accompany Mexican recipes. Palomas couldn't be simpler to make: tequila + grapefruit soda (think Fresca) + a lime wedge. No Fresca? You can substitute grapefruit juice and club soda for the grapefruit soda.
The Paloma is smoother than any margarita, never requires a blender, and the tiny bubbles make it super-refreshing.
