What is THAT!" hollered Josie when I opened the box we'd just gotten in the mail. Floating in the plastic bag inside was a whitish disk with brownish threads hanging from it that looked more than a bit like a very flat jellyfish.
"That," I said, "is a kombucha...thingie," I finished lamely. How to explain to a child what a symbiotic collection of bacteria and yeast (aka "scoby") is? Because that's what we'd just gotten in the mail, a "thingie" commonly called a kombucha mushroom, even though it's not a mushroom at all.
