When I was visiting the Cancun area, the locals there told us that they use Squirt in their palomas. It's definitely better with actual Mexican soda, as they use cane sugar for sweetener. I stumbled upon this drink purely by accident and it quickly became my favorite. It's waaay lighter than a margarita. Use whatever citrus soda floats your boat. With or without salt, it's quite tasty and easy to make. :)

I am mexican and I can tell you for sure that the best flavor for this drink is given by the "Del Valle" grapefruit soda. Try it!!! Its absolutely delicious.

This drink is fantastic! My friends thought I was genius when I served it at Cinco de Mayo. Love the lime- and be a little generous with the tequila!

Really tasty and refreshing. I think fresca tastes funky, so I used Jarritos brand Toronja (Grapefruit) soda that I bought at a latin market. I ignored the proportions on the recipe since I bough a big bottle of soda and mixed it like I would any other simple drink (e.g. gin

Also, this is a lot lower in calories then a regular margarita.
