That would be nice but we don't really have the space.
What is it that make tandoors different? My main incentive for getting one it to cook killer naan breads. The chicken tikka / shiek kebabs taste just perfect on the BBQ already. Is it specifically clay that makes them taste better or would any stone do?
What Im thinking is getting a cheap clay tile, taking the middle tray out of the BBQ and putting the tile right by the flames for 20 mins. When it is super hot I can lift it up, slap a naan on the bottom of it, then lower it back down so the naan is facing the lava rocks. Is that radically different to a tandoor? I know their sides reach unthinkable temperatures but is the air inside them much hotter than 250 degrees?
I can see a trip to B and Q coming up soon!
