Electrickery? Good grief - indirect heating is simply NOT barbi'-ing. Any way, don't people in HK have servants for such menial tasks as indirect heat cookery? Which, it has to be said, is rather girly.
Ah, but the mud crabs tasted delicious, cooked and lightly chilli'd on the electric thingy, albeit with snow falling outside the balcony
(and keep the Boags at a suitable temperature )
