First prepare dough by taking 1 cup wheat flour, 1 teaspoon oil and salt in a small bowl. Incrementally add water in small quantities and knead smooth and soft dough (like chapati dough). Grease it's surface with 1/2 teaspoon oil, cover it with clean muslin cloth and set aside for 15-20 minutes to settle at room temperature.

Now, prepare alu paratha stuffing. Take the boiled potatoes in a medium bowl and mash it until no chunks of potato. Add chopped green chillies, red chilli powder, grated ginger, garam masala powder, sugar, lemon juice and salt. Mix all ingredients properly.

Step-2Divide stuffing into 6 equal parts and give them a shape of ball. Divide prepared dough into 6 equal parts, give them a round shape and press a little to flatten like pattie.

Take 1/2 cup dry wheat flour in a small plate for dusting. Take one dough pattie and coat it with dry wheat flour on both sides. (It will prevent dough from sticking to rolling board). Put it on rolling board/roti making board (chakla) and roll it out into a circle of approx. 4-5 inch diameter using rolling pin. Put one portion of stuffing in the center of it

Wrap stuffing ball by lifting all sides of rolled circle towards top, seal the edges and again give it a round ball shape

Roll it out into circle of 6-7 inch diameter (like roti or chapati). Do not make it very thin by pressing it too much.

Step-7Place it on a hot tava/griddle and cook over medium flame. When tiny bubbles starts to rise on the surface, flip it and reduce flame to low.

Spread 1/2 teaspoon oil around it's edge with the help of spatula and cook for approx 30-40 seconds.

Flip it again and spread 1/2 teaspoon oil around it's edge. Press it with spatula and cook for 30-40 seconds over medium flame. Repeat flip and press process until golden brown spots appear on both sides of paratha. (No need to spread oil after doing it once in previous steps).
