Heat 1 tbsp olive oil in a pan while cutting up the pumpkin into cubes.
Add whole spices - Cumin seeds, fenugreek seeds, green chillies, bay leaves, red chillies, fennel seeds and asafetida. Toast until fragrant.
Add tomato puree, ginger and salt and cook until the oil separates from the “paste”.
Add ground spices - turmeric, paprika, kala namak and coriander powder (except garam masala). Cook for about a minute.
Add pumpkin cubes, saute well and cook on medium high flame until pumpkin starts losing water.
Then cover and bring to medium-low and cook for about 20 minutes.
Every 5 minutes, stir and mix pumpkins with the spicy paste until everything looks red-ish and homogenous.
Once the pumpkin cubes are soft, add garam masala, crushed fenugreek leaves and amchur powder (if using).
Cook on low for another 2-3 minutes.
Top it off with freshly chopped coriander leaves.
Serve with hot with roti, chapati, rice or naan.
