Wash all the veggies well and cut them lengthwise into 2-inch pieces. While cutting veggies, make sure to put the yam, plantain and brinjal pieces in water for a few minutes to get rid of the sticky serum. You can use it after that.
Heat a vessel/pan on firea It is better to use Urali to make aviyal as it has enough width and space to mix the curry around with your spatula.
Cover the pan/Urali and cook till the veggies are nearly done.
Meanwhile, grind together grated coconut, cumin seeds, small onions/shallots, a few curry leaves and green chilies into a coarse form. Do not make it into a paste form adding water. Just a couple of quick runs in the mixer grinder are enough.
When the vegetables are nearly cooked, open the lid and add the cut mango pieces. Mix well.
Cook again without the lid on.
When 90% of the water content has evaporated, add the coconut mixture on top of the veggies and spread it evenly in the vessel. Do not mix everything up for the moment. You can cover the pan so that the coconut too is cooked well.
After some time, remove the lid and mix everything well.
By this time, all the water would have been evaporated and the aviyal would get a semi-dry consistency. Check for salt and add more if reqd.
When done, add fresh curry leaves and 2 v 3 tbsp of coconut oil and close it with a lid to lock the aroma and your aviyal is ready to be served.
If you netsurf for an Aviyal recipe, you'd probably find another hundreds of recipes with variations in ingredients and the one variation in particular would be the usage of raw mangoes, which is often substituted with Tamarind (Vaalan puli), Tomatoes, or even Sour Curd. So, if you would like to go for tamarind pulp or sour curd, add the water in the initial stage accordingly as the tamarind juice and curd would further dilute the aviyal. And if you want your aviyal to be thick or dry which are by and large preferred by people, then, add coconut only after the whole water content has been evaporateda. though both works for me.. You can also add chilly powder instead of green chilies to give that orangish color to the dish though yellow looks yummy tooa... Though this one in particular has been one of my all-time favorite recipes, I have tried out other varieties of aviyals tooa. And I would definitely share those too with youa
And a final word for those who are considering this dish as highly healthy and nutritious coz of the inclusion of the veggiesa let me tell you that this dish is not only nutritious but is infact a Cholesterol factory with a lot of fresh coconut and coconut oil going into it. So, if you do not want to increase that C factor, reduce the oil and amount of coconut accdglya However, I don¦t think Keralites wouldn¦t mind compromising on this since they know that an occasional treat of aviyal, sambhar n thoran as a side dish with rice would definitely make their day along with giving them a satisfaction of having something naadan!!!! And it is certainly something to cherish abouta..!!!!
