Step 1: Gather all your tools and ingredients, including a cocktail shaker, jigger, citrus juicer, glasses, and ice. Have your tequila, fresh limes, orange liqueur, and agave nectar ready.
Step 2: If desired, prepare your glass by rimming it with salt. Pour salt onto a small plate. Run a lime wedge around the rim of your glass, then invert and gently press into the salt, twisting to coat evenly. Set aside.
Step 3: Cut your fresh limes in half and use a citrus juicer to extract approximately 2 ounces (4 tablespoons) of juice. Strain out any seeds or pulp for a smoother drink.
Step 4: Fill your cocktail shaker about two-thirds full with ice. Add 4 ounces of Blanco Tequila, 2 ounces of fresh lime juice, 1.5 ounces of orange liqueur, and 0.5-1 ounce of agave nectar or simple syrup (adjust to your preferred sweetness).
Step 5: Secure the lid on your shaker and shake vigorously for 15-20 seconds, or until the outside of the shaker is frosty, indicating the drink is perfectly chilled and diluted.
Step 6: Fill your prepared, salted glasses with fresh ice. Strain the margarita mixture from the shaker into the glasses. Garnish each with a fresh lime wheel or wedge and serve immediately.
