The Mexican Martini is an Austin original. Basically, you take a martini and substitute the gin or vodka for tequila. Many restaurants in Austin serve the beverage, and each do it with their own twist. The secret is to use fresh juice (instead of a mix or sweet and sour) along with good tequila, olives, and a splash of olive juice. A few of the places that offer the Mexican Martini are the Cedar Door, Takoba, Trudy's, Z’Tejas, Azul Tequila, and 219 West.

Here's one good recipe we found:

Ingredients

• 2 oz. Tequila of your choice. We think a Silver looks the part for a martini!
• 1 1/2 oz. Cointreau Orange Liqueur, Grand Marnier Triple Sec
• 1 1/2 oz. Lime Juice
• 1 oz. Orange Juice
• Splash of Sprite or 7-Up
• No cheap drink mixes!
• 1 splash olive juice to make it authentic and to dirty it up
• Skewered Jalapeno-stuffed martini olives!
• Salted Martini glass rim

And another good recipe we found here:

• 2 oz. Tequila – Use a good silver tequila. The light color makes it look better.
• 1 1/2 oz. Cointreau or Grand Marnier.
• 2 oz. Lime Juice. Don’t use a mix for this drink. Sweet and Sour will ruin it.
• 1 oz. Orange Juice.
• 1 splash Sprite
• 1 splash olive juice – or more to taste.
• Jalapeno stuffed olives!
