01 - Fill two old-fashioned glasses with crushed ice, mounding it slightly above the rim.
02 - Combine orange juice, pineapple juice, lime juice, orgeat syrup, and simple syrup in a cocktail shaker. Shake vigorously for 10–15 seconds until well chilled.
03 - Strain the mixture evenly over the ice-filled glasses, filling each about three-quarters full.
04 - Slowly pour 0.25 oz grenadine into each glass. The syrup will sink to create a beautiful layered effect.
05 - Place an orange slice on the rim of each glass. Add a maraschino cherry and a fresh mint sprig to complete the presentation.
06 - Serve immediately with a straw and enjoy your tropical alcohol-free Mai Tai.
