So Starting with Before
If you have been following me you will know that I currently do a lot of cooking of fish in the Tandoor. So your next question is does the smoke from the fish effect other things you cook. The simple answer to that is NO, and it definitely does not affect cooking naan or even loaves of bread in the often. I should say no one else has complained of smelling or tasting fish when I have used the Tandoor.
One last question, “Why so much soot on the side walls”. I think this is down to me always keeping the lid on before I cook. There is only a small hole in the top for smoke to escape, and hence the soot on the sides. I keep the lid on to help the oven heat up, but I think for the next six months I will leave the lid off. It will be interesting to see if this reduces the soot.
