George had absolutely no doubts whatsoever about how he was going to make his famous medicine. he wasn’t going to fool about wondering whether to put in a little bit of this or a little bit of that. Quite simply, she was going to put in EVERYTHING he could find. There would be no messing about, no hesitating, no wondering whether a particular thing would knock the old girl sideways or not. The rules would be this: whatever he saw, if it was runny or powdery or gooey, in it went.

Nobody had ever made a medicine like that before. If it didn’t actually cure Grandma, then it would anyway cause some exciting results. It would be worth watching.

Yes, I know, it’s Roald Dahl and kids everywhere doubtless love it – but – ewww. I can’t help thinking that this is such an irresponsible book! Put loads of probably poisonous and certainly inedible items in a pot and feed it to Grandma just to see what happens?

(And, yes, just one more story where it is a female relative who is wicked and/or comes to a sticky end. Ho hum.)

Here is an Amazon link.
This is already in my Dahl collection.
