Aviyal - Veggies in a coconut gravy

Aviyal is a traditional recipe from Kerala consisting of color contrasting vegetables in a coconut gravy. Aviyal is a favourite among everyone at both my parents and inlaws place.Both use very different set of vegetables and the gravy varies in consistency too.

Anyway here is my choice of vegetables and my version of Aviyal. Normally vegetables used are ash gourd, chayote, drumstick,raw mango, cucumber,raw plaintain,potato, carrot, beans, peas and yam.
However I have used ash gourd, beans,carrot, peas and potato.

This recipe serves 4

Ash gourd 1 cup
Potato-  1 small
Carrot -2
Beans 10
Peas 1/4 cup
Tumeric powder 1/2 tsp - optional
Sour Curd 1 cup

Seasoning
Coconut oil 2tablespoon
Mustard seeds 1 tsp
Urad Dal 1/2 tsp
Dry red Chillies 3
Curry leaves few

To grind
Shredded Coconut 1 cup
Green Chillies 4

Wash and chop all vegetables into 2" peices.
Take a heavy bottom pan and add carrot, beans and potato. Add sufficient water to cook these veggies. Add salt and turmeric powder.
When these veggies are done add ash gourd and peas( I used frozen peas , hence added at the end ).Let these cook.
Once done, add the ground paste and give one boil.

Let it cool down a bit.Now add sour curds.
Add the seasoning and serve.
Enjoy with hot rice and papadam.

Tip : Do not add curd when avial is still hot, it does not taste good.
Turmeric powder is optional, some like it white.
