Add 1 teaspoon cumin seeds, 1 teaspoon salt to 2 cups All purpose flour and make dough. Cover with damp cloth and set it aside.
In a frying pan heat 1 tablespoon oil and fry 1 teaspoon Black Mustard seeds, 1 teaspoon cumin seeds, 1 teaspoon Garlic minced, 1 teaspoon Ginger paste, and 1 teaspoon chopped Cayenne green chillies.
Add boiled and sliced 2 pounds Golden yellow potatoes, 1 teaspoon Garam Masala, 1 teaspoon Coriander powder, 1 teaspoon Turmeric, and 1 teaspoon Salt. Fry potatoes as you mix gently until they are coated with all ingredients.
Add ½ cup Sweet green peas and mix gently. Reduce to low heat and cook for 10 mins with lid on. Turn off the heat and add ½ cup Chopped cilantro.
Roll the dough into golf ball size and start pressing flat circles. Cut in the center to make half moon shaped. Pickup the half circle in your hand and make a cone shape with straight edge at the opening side.
Add 1 tablespoon of the potato filling and close the cone edges with water coat.
Heat the oil in a deep frying pan at medium heat and slowly add the samosas to the hot oil. Deep fry for 10 mints or until dough turns golden brown.
Cover the samosas in air tight contained until served. Serve warm with a dipping sauce.
