It would seem that Traditional Tandoor recipes are few and far between so if you manage to own your own tandoor can I suggest the book "Tandoor" by Ranjit Rai if you are hunting for recipes.
That's a very good, glossy, high quality book
But I think it's the only book
The problem is that the recipes aren't BIR
They use tenderisers like papaya juice
There are items that you certainly won't be able to buy at Tescos
And if you could get them, they would not be cheap
The book is fantastic though, it gives an illustrated history of the tandoor.
There are pictures of them being made.
If you are a tandoor fan, you will get much enjoyment from this book!!!
As for recipe though, we have the best ones, already on this site
