I don't know if this will work with chipotles, but check out a cookbook by
Graham Kerr called either "Minimax" or "Smart Cooking". They are lf but not
necessarily vegetarian recipes. I know in one of them he smokes chicken in the
kitchen without a smoker cos I tried it once (set the smoke alarm off - but
that was my fault!). From memory it involved a saucepan, tinfoil, earl gray
tealeaves and brown sugar but I can't remember what was in the tin foil,
obviously not the tea leaves AND the chicken... I only have one of the books I
mentioned but have read the other so I will check if it is in the one I have.
PS I am going to be in London for a couple of days (unexpectedly) in a couple
of weeks. any must-go eating places (places to visit too if you want to mail
straight to me)?
