Simple potato curry

Till date I couldn’t cook good dum aloo. Whenever I try to cook dum aloo, it always ends up into potato curry. I understand that, it is not my cup of tea. I should not even try to cook dum aloo. However, few days back I wanted to cook potato curry differently. I just started adding spices, whatever came into my mind. While cooking I could get the fine aroma, at that time I realized the curry was going to taste good. Moreover, it would taste delicious with simple roti.

One big potato (The potato I used was huge)
One-fourth tsp. of fenugreek seeds
One tsp. ginger paste
One tsp. cumin power
One tsp. coriander powder
One-fourth tsp. garam mashala powder
One cup yogurt
One-fourth tsp. or more chili powder
One tsp. of sugar
Three tbsp. of oil
One cup water
Salt to taste
Pinch of turmeric powder

Wash and peel the potato. Cut the potato into cubes. Marinate the potato cubes with salt and pinch of turmeric powder for ten minutes. Heat a heavy bottom wok on medium. Add two tbsp. of oil. Fry the potato cubes for few minutes. Let it cook. Keep the temperature from getting too hot. Fry the potato cubes until little brownish on every sides. Take the potato out from the pan, and keep then in a bowl. In the same pan add another tbsp. of oil. In oil add fenugreek seeds. As you get the fine aroma, add ginger paste into. Fry a little, and add all the dry powder. Ginger paste will stick in the bottom of the pan. So you have to scrape it. Add the fried potato cubes, and mix well with the spices. Meanwhile, in a bowl take one cup of yogurt , sugar, chili powder, and water. Mix well, and it to the pan. Mix well everything. Keep the temperature always in medium. Cover the pan, and cook until the potato cubes are tender. Serve hot with roti.
