Fire is used as the source of energy in this method and the important
leaf which is cured is Jaffna tobacco (a chewing type) in Ceylon and
in Tamil Nadu.
In this method the harvested leaves are wilted for few hours in the field,
tied into bundles of 3 to 4 leaves and hung on racks in a smoke-hut.
They are then smoked for 12 hours by burning coconut husk, leaf, stalks,
etc. and stocked for 3 days and again smoked.
During the smoking treatment the creosotic substances produced from
the smoke are absorbed by the tobacco that impart a particular taste
and antiseptic properties in the leaves.
The leaves are fermented into bulks for 3 to 4 weeks after smoke
treatment and then treated with salt water from the lagoons or with
jaggery for a special or peculiar taste of this type.
