1) Allow to muddle for 2 mins:
* Juice from 2 limes (fresh = better. Key = best)
* 2 Tablespoons agave nectar (honey or simple syrup if you have to)
* 2 limes, quartered, and half of a small orange
2) Strain & shake with 2oz silver tequila & ice.
3) Strain & Serve
It's not like any Margarita you've ever had. You know, unless you've had one of these.
The 2 limes and the half an orange are whole, but I bet squeezing the orange in there would be awesome.
The proper recipe below is from Alton Brown's Good Eats, and includes garnish and technique.
2 ounces 100 percent agave silver/blanco tequila, divided
1 tablespoon kosher salt
4 limes, divided
1/2 small Hamlin or Valencia orange
2 tablespoons light agave nectar
3/4 cup ice cubes, about 3 to 4
Pour 1/2-ounce of the tequila into a small saucer. Spread the kosher salt in a separate small saucer. Dip the rim of a martini or other wide rimmed glass into the tequila. Lift out of the tequila and hold upside down for 10 seconds to allow for slight evaporation. Next, dip the glass into the salt to coat the rim. Set aside.
Halve 2 of the limes. Cut a thin slice for garnish from 1, and set aside. Juice the halved limes into the bottom of a Boston-style cocktail shaker. Cut the remaining 2 limes and the orange into quarters and add them to the the shaker. Add the agave nectar and allow to muddle for 2 minutes until the juices are released. Strain the juice mixture through a cocktail strainer and discard the solids.
Return the juice to the bottom of the shaker, add the remaining 1 1/2 ounces of tequila and any remaining on the saucer. Add the ice to the shaker, cover and shake for 30 seconds. Strain the mixture through a cocktail strainer into the prepared glass, garnish with reserved lime slice, and serve immediately.
