Even intimate family gatherings featured local cooks, affectionately known as “Thakur,”labouring the overall colossal “Kadhais,’ crafting this dish to perfection.
Mutton Kosha or Kosha Mangsho traces its lineage to the kitchens of Bengal, where it evolved from the ancestral Mangsho Kosha, introduced by Odia cooks during British era. Constant stirring and slow cooking over a low flame transforms the humble mutton into a velvety indulgence, rich in flavour and history.
