Can you find a strong enough tin these days to make that lovely little barbecue? I think it is rather good apart from that.
As others say, I would prefer to use wood, although we make and and sell charcoal. English charcoal should light directly with a lighter btw, but I find, having used wood since I was a Guide, that I can control it better than charcoal. We use a storm kettle at shows because we are producing wood shavings and chips all the time which are ideal for fuel for the kettle. On a hot day, a fine wood shaving is virtually seasoned by the time it hits the ground.
