If making homemade simple syrup add one cup of sugar to one cup of boiling water. Stir until completely dissolved and turn off heat. Let stand until cool. Store extra in container in refrigerator. ** If you use raw sugar you will achieve a thicker, more syrup like consistency with a beautiful golden brown color.
Thoroughly wash and remove seeds from loquats. Place loquats in blender with lime juice and blend until smooth. Add simply syrup and rum and blend. Taste and add more if you would like it sweeter.
Fill glass with ice and half of the juice mixture. Top with your favorite sparkling water and garnish with a lime wedge and/or fresh mint. Cheers!
