Potato and onion curry (aloo-pyaz ki sabzi)

This dish transforms the everyday veggies like potatoes and onions into a delicacy. The spices are intense and completely blended. It has rich aroma which fills the house with warmth. This is an occasional indulgence as it is rather heavy. 

I don't know the origin of the recipe, but we used to eat this in winter weddings in our hometown. It was so tasty that we skipped the whole bouquet just to hog on this one.

I've made a few changes and reduced the use of oil. 
Serves 2 very hungry mortals :)
