Very easy and delicious. We make it all the time, with precooked chickpeas.
I have made this several times now and I have to say it is a great dish. The flavour is really enhanced by the addition of Tamarind.
I made a half recipe of this the other night and it was fabulous! I used canned chickpeas instead of dry and used the liquid they came in instead of adding water. I halved everything but the tamarind juice - I love the richness tamarind adds to this dish! My husband doesn't like chickpeas but has agreed to try this recipe next time I make it because he liked the sauce so much. We didn't have cilantro on hand so I substituted a little bit of parsley - not as good, but better than nothing.
The flavor of this is amazing! I rated it a 3 star because I couldn't figure out what to do with the baking powder or bay leaves. Also because cilantro wasn't on the ingredient list I didn't get any at the store. Because I had cooked chickpeas on hand, so I didn't have to do the first five steps.
