Dear Y&Y,
Well I DO consider myself something of a tapioca expert...my friend Dianne in Iowa recovered from pancreatic cancer okay, six years clear now, but the chemo left her permanently unable to eat properly!
So she got down to 78 lb. (that's 5.6 stone to the Brits) and she is my height, 5'6"...before we started collaborating on her nutrition, and tapioca pudding was one food she could tolerate that was reasonably healthful.
You can make lots of interesting variations, bananas, blueberries, etc...well all told she gained ten pounds in six months...felt good...and no longer had episodes of fainting weakness, unable to get up.

So I can make tapioca pudding for you!
