Moyras ( sweet makers ) from Bengal

I understand few people know about the traditional  village moyras (halwai, sweet makers ) of Bengal they can be seen in village melas  only seen in calcutta during the pujas .
this people whom i met at northern park in calcutta they come from Diamond Harbour ....
they sell the mithais in kgs and their items are quite different from what is sold in the mithai stores of calcutta
