Using green pumpkin which is less sweet and yellow green from inside is better for this recipe.
Chop it into bite-sized pieces. Do not peel it.
bring mustard oil to a smoking-hot temperature. Now add asafetida, cumin seeds, nigella seeds, mustard seeds, fennel seeds and fenugreek seeds. This mix of spice is also known as panch phoron.
Once the seeds splutter, add green chili and ginger. Mix in spices: corainder powder, red chili powder, and turmeric powder. Mix well till the spices are roasted and leave aroma.
Now add chopped pumpkin and salt. Mix well.
Cover the pan and allow the pumpkin to cook for 5-10 minutes still slightly tender.
In the meanwhile, strain the soaked tamarind pulp. Set aside.
Remove the lid, and add strained tamarind and crushed jaggery. If you wish to retain the shape of the pumpkin pieces, mix gently otherwise the kaddu will mash up.
Allow the pumpkin to cook for another 3-4 minutes without covering till the jaggery dissolves.
Add garam masala and garnish with fresh coriander.
Serve hot with pooris or chapati.
