First, wash the potatoes well under running water.
Then, peel them if you like, though leaving the skin on is also great for aloo bhaja!
Next, cut the potatoes into small cubes—that's how I prefer them for this recipe. But feel free to cut them into sticks, wedges, or even round slices if you'd rather.
Soak the cut potatoes in water for at least 5 minutes.
Now, heat 2 tablespoons of mustard oil in a pan.
Once the oil is hot, add 2-3 dried red chilies to season the oil. If you like a little more spice, break the chilies apart.
Add the potatoes to the pan and stir to coat them in the oil.
Season with 1 teaspoon of salt and 1 teaspoon of turmeric powder.
Fry the potatoes gently, until they're fully cooked but still firm, not mushy. Frying them on low heat for about 6-7 minutes should do the trick.
When the potatoes are almost done, stir in 1 tablespoon of whole poppy seeds (posto dana) and cook for another minute.
Finally, turn off the heat. Your Posto Dana Diye Aloo Bhaja is ready to enjoy!
