(1) Combine equal parts fresh squeezed pomegranate juice and pure cane sugar in a high speed blender. Blend on high until the sugar is completely dissolved. Store in fridge.
(2) For best results: Use a kitchen scale to weigh the sugar and pomegranate juice (250 grams each) instead of using measuring cups. Add 1 oz pomegranate molasses and 1 tsp orange blossom water to the blender before blending to give the grenadine better depth and more pronounced floral notes.
(3) Bonus tip: If you plan on using your grenadine over an extended period of time (more than a couple of weeks), add 1/2 oz vodka to the recipe and it will stay fresh longer.
