We make peanut butter in our food processor and get the same reaction, people try the peanut butter and love it, then they ask for some, then they want more. I want to say "Buy the fucking peanuts at the fucking co-op and throw them in the fucking food processor, it's not rocket science you moron..."
But then I remember how long it took me to try it, how we burned out our first cheap food processor in a year, how I got different peanuts once and it didn't turn out as well, etc. So some people just aren't interested in spending the time/money figuring these things out, but still enjoy it.
I wouldn't make it to sell. Pretty soon it just becomes work, and it isn't special to them anymore. You burn out your food processor and spend a big chunk of money on a nice heavy duty one, but then their interest dies because it's expensive.
I would just continue to give them small amounts and enjoy the compliments. If they love it enough you can show them how to make it for themselves. But that is just me, nothing wrong with creating a little business if that is what you want to do. Certainly let us know how it goes.
