In the bowl of stand mixer, add all-purpose flour, salt, sugar, baking powder and instant yeast. Whisk all the dry ingredients together.
Attach the dough hook and start the stand mixer on low speed.
Next add yogurt, milk, oil and add one cup of water.
Keep the speed at low/stir and after one min add oil.
Knead the dough for 6-8 minutes.
The dough is ready when it looks smooth and does not stick to the sides of the bowl.
Lightly oil a large bowl and transfer the dough into it.
Rub very little oil. Cover and let it rise in a warm place until it doubles in the volume. This could take about an hour.
When the dough is fully risen, divide it into 8-10 parts and make balls. Rub some oil and let it rest for about 10 mins.
Meanwhile set the oven to BROIL on high.
Take one dough ball, and roll it gently using soft hands. Stretch the dough outwards using finger tips.
You can use a rolling pin to stretch out the dough.
Transfer the stretched dough onto a preheated pan (on the stove).
Keep the flame medium and brush the yogurt and melted butter mixture on the kulcha.
Using a dowel or skinny wooden spoon make holes and sprinkle sesame seeds on the kulcha.
Once the bottom of the kulcha (bread/naan) changes color to light golden, transfer it to a preheated oven and place the kulcha on the top grill.
It will take about 1-2 mins for the kulcha to be fully cooked.
