Prepare the Glasses: Rim your margarita glasses with a wedge of lime, then dip them in salt. Set aside.

Juice the Fruits: Squeeze the oranges and limes until you get the required amount of juice. You can use a citrus juicer for this job.

Combine Ingredients: In a large pitcher, mix together the orange juice, lime juice, tequila, triple sec or Cointreau, and agave syrup or simple syrup.

Shake It Up: Fill a cocktail shaker with ice. Pour a portion of the mixture from your pitcher into the shaker. Shake well until chilled.

Serve: Fill the salt-rimmed glasses with ice. Pour the shaken mixture into each glass.

Garnish: Garnish with orange slices and lime wedges. Serve immediately and enjoy!
