Pour a shallow layer of kosher salt onto a small plate or saucer. Run a lime wedge around the rim of your margarita glass, making it wet enough that the salt adheres properly. Roll the rim in the salt until it's evenly coated, then set the glass aside on the counter.

Add a generous handful of ice cubes to your cocktail shaker or mixing glass.

Using a jigger, pour exactly 1.5 ounces of your bourbon into the shaker over the ice.

Measure out 0.75 ounce of silver tequila and add it to the shaker.

Squeeze fresh lime juice until you have 0.75 ounce, then pour it into the shaker.

Measure 0.5 ounce of Cointreau or your chosen orange liqueur and pour it in.

Add 0.5 ounce of agave nectar to the shaker.

Close your shaker and shake hard for about 10 to 12 seconds.

Using a fine mesh strainer or Hawthorne strainer, pour the mixture into your prepared glass. Pour slowly and steadily for better control, filling the glass until it's about three-quarters full.

Place a lime wedge on the rim of the glass, or squeeze it over the top and drop it in. Serve immediately while the drink is cold and the flavors are bright.
