No idea Phil, I was fascinated by the idea so followed the link (on an iPad) and it didn't work for me, so after some googling found and copied the next link which worked for me (again on an iPad maybe the original still works on a PC)
Anyway, the bottom line is that I put 3 cloves of garlic in my smallest saucepan put the lid on, shook it violently about 10 times and bingo! 3 perfectly skinless cloves. So to others posting earlier in the thread, no waste of a whole bulb and shaking a small saucepan 10 times didn't tire my wrist 😉
it was a bit quick though! 😂
