SAN ANTONIO — If there’s one thing San Antonio is good at (and we’re good at a lot), it’s making a mighty fine margarita, which comes in handy on National Margarita Day.

Although the true origin of the margarita is unknown, one story goes that the drink was first concocted by Mexican restaurant owner Carlos (Danny) Herrera in 1938.

It's said that he made it for Ziegfeld showgirl Marjorie King. According to National Geographic, King was allergic to all forms of alcohol except tequila, but didn’t like to drink the stuff straight. Herrera supposedly solved the problem by adding salt and lime and creating the world’s first margarita.

A classic margarita is simple:

  • 3⁄4 oz fresh squeezed lime juice

  • 1 oz Cointreau, triple sec or another orange liqueur

  • 1 1⁄2 oz

  • Blanco tequila

  • Kosher salt for rim (optional)

Several variations are found far and wide, and you can find margaritas of various flavors. Margaritas are the most common tequila cocktail in the U.S., served on the rocks, frozen, or straight.
