Heat 1 tablespoon of oil in a pan over medium heat. Add the cumin seeds, coriander seeds, chana dal (Bengal gram), green chilli, ginger, and asafoetida. Fry for about 3 – 4 minutes until they turn aromatic, and nutty.
In the same pan, add the chopped bottle gourd cubes, and salt. Cover and cook on medium flame, stirring occasionally. Bottle gourd releases water, so let it cook in its own juices until the pieces are tender and cooked through (about 8 – 10 minutes).
Turn off the heat. Add chopped mango, and coriander leaves. Mix, cover, and let it cook in the steam while the ingredients come to room temperature.
Add cooked ingredients into the blender along with 2 – 3 tablespoons of water. Pulse a couple of times. A coarse texture is absolutely fine.
Heat remaining of oil in a small pan. Add mustard seeds, and split urad dal. Fry until the dals turn a golden brown.
Once they begin to splutter, add the dried red chili, and curry leaves. Let the curry leaves crisp up for a few seconds. Turn off the heat and pour this sizzling aromatic tempering directly over the ground pachadi. Mix well.
Serve Sorakaya Pachdi with hot rice and ghee.
