The missus and I went on a bit of a road trip to deepest Kent yesterday to pick up my new toy. A portable propane tandoor which I got off eBay for ?60. Not a bad buy I thought but I think it needs a little work doing to it before use.
The main problem is it is a little rusty, notably on the inside where it is fine and powdery - not good for sticking naans to!
I'm thinking (unless there is something more suitable?) of buying some fire clay as used in homemade pizza ovens and lining the inside with it - to maybe 1/2" - 1" thickness. Hopefully this will also increase its heat retention properties and thus save on gas. Not sure whether I need to prime the surface in any way to form a 'key' for the clay to stick to?
I'm just wondering, do I need to put clay balls in the bottom of it or even charcoal for that fabled smokey flavour?
I know there's one or two people on here who have refurbished tandoors. Any hints and tips would be gratefully received.
