When I ask people what they think grenadine is they always say.....cherry juice.
Grenadine is a red syrup that was originally made from pomegranate juice, cherry juice and sugar. Not just cherry juice like most people like to believe. In fact, grenadine actually comes from the French word, "grenade" which means pomegranate. Now grenadine consists almost entirely of a high-fructose corn syrup base. Yummers!
Grenadine is used to make drinks like "cherry" cokes, pink lemonades, shirley temples and tequila sunrises.
So if someone asks you what grenadine is, you can tell them the correct answer. It isn't really just cherry juice. It's actually pomegranate juice with a bunch of sugar.
