This was very good, the broth was very flavorful. The chicken was a bit bland - to be expected with chicken breast, not my favorite meat, but I happened to have some. I think lamb would have been better. I did not use the cinnamon. I squeezed a little lime juice into the serving bowls rather than cooking with it.
Just a guess but I think probably the original recipe used loomi instead of lime juice as they are used a lot in Persian cooking. It would impart a different flavour than lime juice it self though it is dried lime.
