Choose what you call it, if in India, you will call it Dry Potato Sabzi / Curry, or Sookhi Aloo Sabzi (सुखी आलू की सब्ज़ी), or if you in western country, its more commonly known as Bombay Aloo or Potato, it is one of the simplest curry made of potatoes with spices. Its magical to see how simple spices can add so much flavour to potatoes.
This curry is absolutely easy and quick to make and is ready in less than 20 mins. You can have this as side dish with you main meal, or can simple eat this with chapatti, puri, or stuff it in between bread slices and make a grilled sandwich.
I normally make this at least once a week, as it acts as side dish, and I feed it to my young one, who likes to have it as sandwich.
You can make this in two ways, either you can make it with boiled potatoes or you can use fresh potatoes, and use directly. If you have a busy schedule, you can always keep potatoes boiled and ready in your fridge, and then use this recipe to get curry ready in 15 mins. My recipe described here is with boiled potatoes.
