Yeah, I'm not sure to be honest!  Water extraction does work, but not as well as an extraction with ethanol or a fatty substance like milk.  Milk seems to be the one that is closest to regular nutmeg but has less side effects, at least to me.

Space paste is one of my favorite preparations, but eating it isn't that delicious, so I do it rarely - although, I did recently make space paste chocolate rounds that I ate and had great effects from, and the taste was not as much of an issue.  I'm trying out different cooking experiments to see the most palateable mixture for me to make with space paste.  I'll keep you posted.  Glad to see people are still trying things.  I'm going to post the space paste chocolate in another thread.
