My dear boy, I would have you know that I eschew all ex-colonial products along with anything that originates from across the English Channel, and indeed, from far Cathay.Have you thought the logistics of this through?
jelly is very runny when you make it, are you going to let it partially set before pouring it in?
do you have a fridge big enough to help it set?
how are you going to empty the berghan of jelly? I'd just set it between my kids and give them a spoon each. 180 litres of the stuff should be gone in about an hour
I've had a horrible thought, what if by 'jelly' you are referring to some ghastly American product?
As for your questions as to my competence in dealing with gelatinous products, I once ate a two gallon bucket of raspberry flavour jelly (Hartley's) for a bet (obviously not the plastic bucket itself) at my old rugger club.
