Make a simple syrup with 3 tablespoons and ½ cup of water. Add the sugar and water to a small saucepan over medium heat. Stir until the sugar is dissolved. Take it off the heat and allow the syrup to cool.

Extract the lemon juice using citrus juice or handheld juice. Strain and set aside.

Mix pomegranate juice, lemon juice, and syrup until blended. Strain the mixture into a jug or pitcher and add the additional cups of water or sparkling water. Stir well.
