For mint syrup:
In a small saucepan over medium-high heat, bring the water and sugar to a boil, whisking to dissolve sugar. Reduce heat, add mint leaves and simmer for 5 minutes. Remove from heat, allow to cool.
For punch: To a Cazuela or punch bowl stir together agua de Jamaica (hibiscus), fresh lime juice, mint syrup, tequila, orange liqueur. Add ice, then top with Fresca or Squirt Mexican soda. Garnish with lime slices and fresh mint.
