How to Make Simple Syrup - Make your simple syrup by combining the sugar and water in a small pot, heat and stir until all sugar is melted. Remove from heat, cool. Once at room temp, pour into a mason jar, put a lid on it and store in your fridge until ready to use.
Homemade Lime Soda
Supreme your limes (peel with a knife and cut into segments).
Set aside the lime segments. Squeeze all skin juice and leftover lime pulp juice into a small mason jar. Squeeze additional limes into the jar as well (1 or 2).
Grab a tall glass, plop a few lime segments into it, muddle. Add in lime juice and simple syrup (start with 1 TBS and add more later to get to your preferred level of sweetness).
Fill glass with ice, top with seltzer, stir, taste and adjust for sweetness and enjoy!
