Ingredients: 

For the samosa stuffing:

shelled green peas ½  cup(s)
oil 2  tablespoon(s)
cumin seeds 1  teaspoon(s)
finely chopped 2  green chillies
finely chopped ginger 1  teaspoon(s)
potato(es) peeled and cubed 2  large
red chilli powder ½  teaspoon(s)
salt to taste
dry mango powder (amchoor) or lemon juice ½  teaspoon(s)
garam masala (hot spice mix) ½  teaspoon(s)
chopped coriander leaves 2  tablespoons 
 

For the samosa shell:

plain flour (maida) 1  cup(s)
baking soda ½  teaspoon(s)
baking powder ½  teaspoon(s)
carom seeds ½  teaspoon(s) (optional)
Ghee (clarified butter) / oil 3  tablespoons
salt to taste
water as required for kneading
oil to deep fry

Preparation of Punjabi Samosa:

   1. Cook the peas in boiling salted water for about 10  minute(s) or till soft. Refresh in cold water and drain well.
   2. Heat the oil in a pan. Toss in the cumin seeds and let them crackle. Add the green chillies and ginger. Fry briefly. Add the potato cubes and mix well. Add the red chilli powder, salt, dry mango powder and garam masala powder. Toss well. Sprinkle some water. Cover and cook on low-medium heat for about 10  minutes or till the potatoes are cooked. Mix in the cooked green peas and put off the heat. Let cool. Mix in the coriander leaves.
   3. To make the samosa pastry shell, sieve together the plain flour, baking soda, baking powder and salt. Mix in the carom seeds and ghee / oil. Add water little by little whilst mixing with fingers to make a stiff dough, the consistency of a shortcrust pastry. Keep covered with a damp cloth for about 15 minutes.
   4. Divide the dough into 16 equal balls. Apply a little dry flour to each ball when rolling into a circle of 4″ diameter. Cut each circle into two and lightly dampen the edges of each semicircle with water. Shape each semicircle onto a cone by pressing the cut edges together. Place a spoonful of the potato-pea filling into the cone and seal the edges well (apply some water on the edges if they do not seal well). Repeat this procedure with the rest of the balls. Deep fry in medium-hot oil in batches on medium flame till crisp and golden brown. Remove onto a paper towel.

TIPS:

    * To save on time, potatoes can be pressure cooked and then cubed and tossed in spices.
    * Carom seeds are also called as omum, caraway seeds, thyme seeds and ajwain.
    * Chillies can be increased or decreased as desired.
    * The samosa pastry shell can be made with plain flour without the baking soda and baking powder.
    * Self raising flour can be used instead of plain flour, in which case omit the baking soda and baking powder.
