Soak chickpeas for 4 to 5 hours or overnight. Drain water and keep it ready.
Wash and peel off elephant yam, chop it in to medium sized cubes. Similarly peel off onion and chop it in to cubes. Soak tamarind in 1/4 cup of water for 10 minutes, extract it's juice and discard residue.
Method
Heat a pan adding all the seasoning ingredients in the order mentioned, when the mustard seeds sizzle and pop, include onions. Saute them till translucent, then add chopped yam and chickpeas.
Saute the veggie for a while and add a cup of water. Let the yam cubes turn little soft and then include tamarind juice, jaggery and salt. When the yam and chickpeas get cooked to perfection, add sambar powder.
Let the veggie and chickpeas nicely absorb flavors. Finally add fresh grated coconut, adjust consistency of the curry by adding water. Bring it to boil and switch off.
This easy elephant yam curry is wonderful with steamed rice.
Notes
I have used the sprouted chickpeas for extra nutrition. You too can sprout them before using.
This yam curry tastes good being little sour, sweet and spicy.
I haven't added any chillies for spice. You can add one or two green chillies if you prefer.
Fresh coconut is used to make the curry thick, do not skip it.
