Deseed and cut the Mangalore Cucumber into chunks, leaving the skin on.
Boil it with salt to taste until tender.
Dry roast the chillies, whole coriander, cumin, urad dal, chana dal, and sesame seeds.
Add the grated coconut and turmeric to the pan and continue roasting until the coconut starts to brown slightly.
Allow the roasted ingredients to cool down, then grind them together with the tamarind and jaggery to form a smooth paste.
Add this ground paste to the cooked Mangalore Cucumber and bring it to a boil.
Meanwhile, prepare the tadka. Heat the coconut oil and add the mustard seeds. Once they start to sputter, add the curry leaves. Pour this tadka over the boiling Kodhel and turn off the flame.
Serve hot with rice, papad, and pickle. Enjoy your Thauthe Puli Kodhel!
