Ask Dr. Knowledge - Real licorice, which is in black licorice candy, is made from the roots of the licorice plant, which can also be spelled liquorice. Red licorice isn’t really licorice at all, except in name. It’s just a red candy, which can be made with many different flavorings, including strawberry, cherry, raspberry, and cinnamon. Despite similarities in taste, licorice is not related to anise or fennel. American, Chinese, and European varieties of the licorice plant are all slightly different but have many similarities.
Yea, what he said, and also, Black licorice is fucking disgusting. Are you kidding me Dr. Knowledge? You take the time to research an extremely well thought and scientific answer and you miss the most obvious difference (aside from actual color)? I don't care what it's made out of, I'll eat that red rope candy by the pound, I will not go near black licorice or black jelly beans to save my life. That's the real difference.
Side note: How is it that candy companies even still make black licorice? I mean how many people actually like this stuff? 1-100? 1-500? It's gross. I know 2 people that like it. 2! Out of everyone I know and have met. I just can't see how that's a profitable business to be in.
