So I had the bright idea of putting excess kefir grains in porridge... I waited for it to cool enough to be edible then mixed it in.
At first it was fine, just the odd bit of sour in a bite. Then it rapidly turned into the consistency of what I can only call mucous... At first I tried to ignore this and keep my imagination at bay, until the texture had spread throughout the entire porridge and I found myself involuntarily spitting it out; near throwing up. I found it inedible at that point.
Any idea why this had happened, some sort of heat reaction? Have I ingested anything harmful?
