Peel and cut potatoes in cubes.

Heat oil for deep frying in kadai, once hot put potatoes and fry till done, you can keep flame medium low and cover and cook for 3-4 mins for faster cooking

Once potatoes are cooked fry on high flame, for 3-4 mins till they are crispy, they done have to change color

Now remove excess oil, add salt and rest of spices and mix properly, so that you get nice color, sprinkle 1 tablespoon water, cover for a minute or two and its done

For sevaiyaan

In a kadai add ghee, put crushed cardamom, now simmer the flame and add sevaiyaan (I have used roasted), roast for a minute or so
If using raw sevaiyaan increase amount of ghee and roast till you get a nice color.

Now add water and allow it to cook, keep flame medium.

Once water dries up add sugar and cover and keep for a minute

Let sugar melt and caramelize giving it a nice color, mix gently
