Yes it has a gas bottle. Yes it's used for setting fire to the coals. No, it isn't used for cooking on.
Ah, but you can go 'commando' without the gas bottle.
As I wrote last year on this thread, Mrs. history took upon herself to upgrade my tried and trusted pure charcoal culinary shrine while I was deployed. My friend of many years, nay he even served my father before me, was cast to the pavement and I never got to say goodbye.
She replaced my friend with this contraption but I had to put it together upon my arrival home.
After grieving for my long lost grill (I think I've come to terms with the loss), I put 'this' together, but sans the gas hook up or, as has charmingly been put on this thread, the 'fiddly bits,' and use strictly the blocks of manliness occassionally with exotic chips of wood.
Woman, know thy boundaries!
