I’ve not eaten the pulp out of KCT pods. I’m of the understanding that it can be used as a ‘soap substitute’ for handwashing, etc. Really works up a nice froth.
Seems like Mike Dirr admitted (tongue-in-cheek?) that perhaps some of his personality quirks were a result of having eaten that goo as a kid. The KCT seeds, however, do contain toxic alkaloids - unlike those of honeylocust, which could, conceivably be ground into a useful flour - but it has been suggested that roasting inactivates the alkaloids in KCT seeds… but early settlers who bought into land speculators’ claims that KCTseeds made an acceptable replacement for coffee… abandoned roasted KCT seeds for ‘real’ coffee as soon as it became available on the frontier.
