Alton brown's awesome hand-mixed margarita

1. Halve 2 of the limes, cut a thin slice for garnish from 1, and set aside.

2. Rub a lime wedge around the rim of a wide-rimmed glass to moisten. Spread the kosher salt in a separate small saucer. Dip the glass into the salt to coat the rim. Set aside.

3. 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 juice in the shaker. Add the agave nectar to and muddle for 2 minutes (two WHOLE minutes, do not skimp on this part!). Strain the juice mixture through a cocktail strainer into the top of the shaker and discard the solids.

4. Return the juice to the bottom of the shaker, and add the tequila. 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.
