A bunch of pumpkin or other winter squash
Kari leaves
Dried hot peppers
Ginger
Fenugreek seeds
Asafoetida
Coriander (it's cooling, it balances the hot spices)
Turmeric
Ghee or oil

1. Heat ghee/oil. Add kari leaves, hot peppers, and ginger.
2. Add fenugreek, asafoetida, coriander, and turmeric (after the ginger, otherwise it'll burn quickly).
3. Add pumpkin chunks, cover and roast dry for a while.
4. Add salt and cook more. (salt draws out the water, so after you add salt, it'll begin steaming, not roasting.)
5. Add some other stuff that I missed when she was giving instructions.
