To make the simple syrup:

• Combine 1 tablespoon of liquid monk fruit sweetener with 1 cup of water.
• Store in an airtight container; it’ll last several weeks in the fridge.

To make the mango margarita:

• In a blender, add the mango squeeze pouch, tequila, simple syrup, and lime juice. If making a frozen margarita, add the ice as well. 
• Blend until well incorporated.
• Wet and salt the rim of your glass and fill it with ice (unless serving the margarita frozen).
• Pour the margarita into the glass and top with sparkling water if you’d like to add a citrus flavor most margaritas have.
