In a wide plate, mix all-purpose flour, salt, and carom seeds. Gradually add 1/4 cup of oil to the mixture, followed by water to form a semi-soft dough. Apply oil on the dough, cover, and let it rest for 15-20 minutes.
Heat 2 tbsp oil in a pan. Add cumin seeds, asafoetida, and coriander seeds. Then add chopped green chilies and grated ginger. Stir in green peas and mashed potatoes.
Add coriander powder, Kashmiri red chili powder, cumin powder, turmeric powder, and garam masala to the potato mixture. Mix well.
Season with salt, dry mango powder, and Kasuri methi. Stir in chopped coriander leaves and remove from heat.
Knead the rested dough again and divide it into small portions. Roll each portion into an oval shape and cut it horizontally.
Take one portion of dough, wet the edges with water, and form a cone shape. Fill the cone with the prepared potato mixture and seal the edges tightly.
Repeat the process with the remaining dough and filling.
Heat oil in a pan for frying. Once hot, fry the prepared samosas until golden and crispy.
Drain excess oil and transfer the fried samosas to a plate lined with paper towels.
Serve hot with green chutney, tamarind chutney, or your favorite dipping sauce. Enjoy the crispy and delicious Aloo Samosas!
