In a pressure cooker, add one-hour soaked toor dal, chopped onion, tomatoes, green chillies, peeled and halved garlic pods, turmeric powder, and a little oil. Pressure cook for 3–4 whistles until the dal is soft and well-cooked.
In the same cooker, add finely chopped palak (spinach) leaves, tamarind water, and salt as required. Close the lid and cook for 2 whistles.
Mash the mixture well, then add the Xtra Flavours Sambar Powder and cook again for 2 whistles.
For seasoning, heat oil in a small pan. Add mustard seeds and let them splutter. Add cumin seeds, followed by crushed garlic pods. After a few seconds, add Guntur chilli and finally curry leaves. Turn off the flame and pour this seasoning over the cooked palak pappu.
Note: I have not used hing/asafoetida in the seasoning because the Xtra Flavours Sambar Powder already contains it.
Mix everything well. Adjust salt if needed.
Serve this delicious Andhra-style palak pappu hot with rice and ghee, chapati, or dosa.
