In a mixing bowl, combine ½ cup wheat flour, 1.5 cups maida, salt, sugar, and oil. Mix well.
Gradually add ¾ cup lukewarm milk while kneading to form a very soft dough.
Transfer the dough to a tabletop, sprinkle some oil, and knead well using the stretch and fold method for 5-10 minutes.
Shape the dough into a ball, place it in a greased bowl, drizzle oil over the surface, cover it with a damp cloth, and let it rest for at least 30 minutes.
Prepare a saltwater mixture by mixing salt and water in a bowl.
Heat an iron tawa or roti tawa over high heat. Once hot, sprinkle salt water over it to create a non-stick coating.
To make the rumali roti, take a portion of the rested dough, form it into a roundel, coat it with refined flour, and roll it out.
Apply some ghee on one rolled roti, place another rolled roti on top, stick them together, and roll it out as thin as possible.
Place the roti on the hot tawa. Cook for 10-15 seconds on each side until tiny brown spots appear.
Once cooked, apply some butter on roti and fold the roti.
