In a mixing bowl, combine wheat flour, all-purpose flour, baking powder, baking soda, yogurt, salt.
Rub until all the ingredient combines well.
Add water little at a time to make a smooth, soft dough.
Sprinkle vegetable oil and spread all around the dough.
Cover it with a lid.
Set aside for four hours.
Making the onion masala
In a mixing bowl, add chopped onion, chopped cilantro, cumin seeds, carom seeds, red chili powder, and salt.
Combine them well.
Prepping the kulcha
After ther resting time, dough turns soft than before.
Now divide the dough into 10 equal sized balls. Set aside.
Dust the board with the flour.
Keep a dough ball and using the rolling pin spread it like a thick and small circle.
Place a tablespoon of onion masala at the center.
Grab the edges together to the center and press gently to make a bigger ball now.
Again carefully roll to a smooth ball by keeping the filling intact.
Cooking the kulcha
Heat a pan in medium heat, place this flat kulcha.
Brush ½ teaspoon of cooking oil and cook for 1-2 minutes.
Flip to the other side, and brush ¼ teaspoon of vegetable oil and cook for 1-2 minutes or until black spots seen.
Remove from the pan and transfer to a plate.
Repeat the same procedure for the remaining dough balls.
And serve hot with raita.
Notes
Rolling with the stuffing inside is tricky and to achieve them perfect, roll gently by applying pressure evenly.I have used onion seeds/kalonji as a topping for kulcha. This step is optional to use. You can use or skip according to the availability of this ingredient.
