Another perfectly crummy alternative to C/Java: chicory
It was foisted on the US public during WW-II so the GIs could get the "real" stuff (not sure they did.)
In the 70's (when I sorta grew up) it was touted as healthier - just like carob was better than chocolate. Hah!
It is also highly touted in NOLA but usually backed by real java.
Chicory has a very new-age ring to it, don't you think. And the releases could start at Chic-18.104.22.168.
