Rim The Glass - Rub a lime wedge around the rim of a 8-10 ounce glass. Dip the rim in the kosher salt on a flat plate. Fill the glass with ice. Set aside. Pro Tip: If you are having more than one margarita (duh!), instead of rimming the glass on the second or third drink simply sprinkle a pinch or two of salt straight into the drink!
Make the Margarita - Place a few cubes of ice in a cocktail shaker. Add the fresh squeezed lime juice, Cointreau, agave, and tequila. Shake for about 20-30 seconds.
Serve - Strain into the prepared glass. Garnish with a lime wheel or wedge.
Optional, but recommended- if you like a few bubbles in your Margarita you can top it off with 1-2 ounces of soda water.
Use a good silver tequila. I find that Casamigos ($$$) or Jose Cuervo Tradicional ($) are both great at varying price points.
Don't skip the agave, it adds just the right amount of sweet to balance the tart lime and salty tequila.
If you have a second or third margarita skip rimming the glass with salt to keep things simple. Just sprinkle a little pinch or two of kosher salt right into your Marg. So GOOD!!!
Virgin Margarita: If you want a non-alcoholic version this Margarita Mocktail is absolutely delicious!
