Roll the limes and lemons on the counter to loosen juices. Cut and juice enough limes to yield 1 cup of fresh lime juice and enough lemons to yield 1/4 cup lemon juice. Strain the juices through a fine mesh sieve into a measuring cup to remove pulp and seeds.

Combine sweetener and liqueur

In a medium mixing pitcher, combine 1/2 cup agave nectar (or simple syrup) with 1/4 cup orange liqueur. Stir to incorporate. Add 1/2 cup cold water and the strained citrus juices. Stir until uniformly mixed. Taste and adjust sweetness — add up to 1-2 tablespoons more agave if you prefer sweeter margaritas.

Chill the mix

Place the prepared margarita mix in the refrigerator while you prepare glasses and ice, or use immediately for cocktail shaking.

Alcohol

Combine tequila with mix

Measure 1 cup blanco tequila and add it to the chilled margarita mix. Stir gently to combine. This batch yields small margaritas (about 6 small cocktails — see servings).

Garnish & Rimming

Prepare glass rims

Pour 1/4 cup coarse salt onto a small plate. Rub a lime wedge around the rim of each glass to moisten, then dip the rim into the salt, twisting to coat evenly. Set prepared glasses aside.

Shake and serve (single cocktails)

Fill a cocktail shaker halfway with ice (about 1 cup). Add roughly 1/3 cup (80 ml) of the prepared margarita + tequila mixture per small cocktail (adjust to glass size). Shake vigorously for 10–15 seconds until well chilled. Strain into the prepared salt-rimmed glass over fresh ice. Garnish with a lime wheel or wedge.

Build in a pitcher (batch service)

If serving multiple people quickly, fill a pitcher with ice and pour the full margarita mixture over the ice. Stir once to chill and dilute slightly. Pour into salt-rimmed glasses filled with fresh ice and garnish each with a lime wheel.

Serve

Serve immediately while cold. Offer extra lime wedges on the side for additional tartness.
