The intention was as per
http://cindalouskitchenblues.blogspot.com/2008/04/coconut-milk-yogurt-at-last-dairy-free.html ...except I also added (unsweetened) pectin. Mistake. Little globs of unincorporated pectin remained, stir as I might. I couldn't toss it in the blender because it hadn't been pre-sterilized, and time ran out (temperature-wise), so I had to just go on with the probiotics and go for it. When I put it in the jars I tried to avoid pectin globs but I'm sure some are in there.
I WILL master this coconut yogurt thing.
Besides the probiotics, coconut contains caprylic acid (also very beneficial).
YUM! CAPRYLIC ACID JUST WHAT I ALWAYS WANTED
Just kidding, really, I hope we will like unsweetened coconut.
p.s. I surely just ruined the probiotics in one of the jars by sticking my fingertip in it to see if it set. Brilliant.
update, next morning: The Disaster is complete. I have never seen anything bubble itself entirely out of a jar in one bubble like that before. The whole house is somewhat pleasantly scented by burnt coconut, and I may have ruined a pot, only time will tell.
