Add curry leaves, raw peanuts, urad or moong dal, cumin seeds, coriander seeds, mustard seeds and dry red chilies.
Roast them on low heat while stirring continuously.
If using fresh curry leaves, they will begin to change their colour. Keep roasting.
Soon curry leaves will turn dry and crisp. If using dry leaves, their colour will not change but still you will find all the ingredients well roasted.
Remove the pan from the heat and let the ingredients cool down completely.
Transfer the roasted ingredients in a grinder jar.
Also add turmeric powder, dry mango powder and salt.
Grind coarsely. Keep aside.
Heat oil in a pan.
Add potatoes (boiled, peeled & cubed).
Roast them while stirring occasionally until they turn golden brown.
Add the powdered ingredients.
Mix well so that potatoes get coated with masala so well.
Curry Patta Aloo are ready. Enjoy as a snack or with roti or paratha.
