Mix the Dough Ingredients - Flour with Salt, Baking Soda, Baking Powder, Vinegar, Sugar, Garlic, Yogurt, and Oil. Make a pillowy soft dough. Add the Lukewarm water and Milk as per requirement. Add 1 tablespoon of water at a time and knead a soft dough. Don't make the dough too dry. The dough should be very soft.
Allow the dough to rest in a warm place or a pre-heated oven for 60-90 minutes. Turn off the oven after you've pre-heated it and just allow the dough to sit there covered for about an hour. The dough will rise considerably at this time.
In a mixing bowl add butter, minced garlic, cilantro.
Pull out your rolling board and grease the rolling pin with oil. Roll out the ball in an oval shape or oblong shape. It should be about 0.5 cm thick, about 7-8 inches long and about 3.5-4 inches wide.
Apply the butter mixture on the rolled out naan bread. Sprinkle some Nigella seeds on it.
Slowly pick up the bread and carefully flip it over to apply water on the other surface. Moisten the surface nicely with water so that it sticks to the cast iron skillet.You could just wet your hands and them pick up the rolled out naan bread. Your wet hands will automatically moisten the other surface of the bread. You won't have to flip it and get all the butter in your hands.
Heat the cast-iron skillet. Place your Naan bread on it - Waterside down. Use a fork to poke small holes in it and keep the flame to medium.
After about 2 minutes, flip the skillet over and allow the butter side to get roasted.
Flip the Skillet back and pick up the bread and top it with some more butter.
Serve with any dish or curry of your choice.

Notes
The Naan Bread dough should be soft.
If the dough is very dry add water or milk.
Do not over-knead your dough.
Allow the dough a bit longer than you think. Otherwise, it might get really difficult to roll out the dough and it will start breaking.
Always use Cast iron skillet or a steel pan to make naan bread. Never use a Non-Stick Pan.
You can also cook it in Cast Iron Griddle.
If you don't have gas, then use a butane torch to torch the top and then turn it over.
If you don't have Yogurt, you can always use sour cream as a replacement
If you don't want to use dairy items, then use Almond milk in place of skimmed milk
You can stuff these Naan with spiced mashed potatoes or mashed Cottage Cheese (Paneer).
If you have leftover Naan, you can freeze it in and before having it heat it on the stove or pop in the oven in full power for 10-20 seconds.
