Mastawa is quite similar to Indian khichadi. Its usually made with Lahndi, a dried meat that is rubbed with salt and asafoetida to preserve it during the winter months. It was believed that Pashtuns who travelled from Afghanistan to Pakistan in to India had to carry rations as nothing was available in the Khyber Pass so they carried Lahndi and rice to make Mastawa.
Mastawa is filling and nutritious and perfect for a long journey. It is simple, delicious and nourishing for the cold winter months.
