Did you ever eat them when you were a kid? We used to all the time. TFA sells the flavoring, got a tiny bottle, mixed some up. Kinda reminds me of how those tasted, but stonger, even at 1.5%. It might be a nice additive, but to what, I don't know. I don't see that one talked about, really. You could post in the DIY section and possibly get more info.
