Soak the small lime sized ball of tamarind in the warm water and set aside for 10 minutes
Once soft muddle the tamarind and extract the soft pulp in the water. Remove the unwanted hard bits and strain the tamarind pulp. Set aside until use
prepare the vegetables
Wash and clean the vegetables needed.
Remove the central part of the bitter gourd, the snake gourd and winter melon. Dice the vegetables about 1-inch cubes.
In a cooking pot add two cups of water, the diced vegetables, salt and turmeric and bring to a boil.
Add the precooked channa ( chickpea) to the vegetable combo. ( you can use yams in the place of channa)
Now add the tamarind pulp prepared to this mix
Cover and cook till the vegetables are soft.
for the poricha kozhambu masala mix
In a separate pan, dry roast the dals and the spices on a low heat.
Once they are crisp add the curry leaves and roast till the curry leaves snap.
Cool this mix and powder it in a spice blender.
Completing the curry
Add this masala mix to the cooked vegetable mix and stir in without any lumps.
Simmer this on slow heat till the gravy thickens and the flavours mix well. This takes about 5-8 minutes on low heat.
The curry is now ready to be served. Enjoy with steamed red rice and crisp vadams.
Notes
For the full fiery version
Use 1 tbsp black pepper and 7-10 red chillies in the masala mix to roast and powder. I have toned down this very much to suit my family.
