I have to ask for those of you that watched it, why AS said "why did you even think of a garden centre to look for a cloche?"
Well a cloche is something like a poly or glass tunnel or cover to protect or to raise young plants, and my second thought was it's a ladies hat! How were they supposed to know which one it was, and then it turns out to be something for the kitchen! Not being a chef, I'd never heard of it!
No time for the net as such Linda, they were supposed to buy 10 items in the one day xx
