When pomegranates are in season -- typically from October through February -- I become somewhat of a fresh grenadine evangelist. Firstly, few people know what it really is – Shirley Temples and that candy red, mass market syrup come to mind. But the "grenadine" you get from a typical grocery store shelf or see behind budget bars is NOT true grenadine. Grenadine is a fresh pomegranate syrup. That supermarket stuff is literally just corn syrup dyed red (ew).
