• 4 cups flour
• 1 teaspoon baking powder
• 1 teaspoon salt
• 2 cups plain yogurt
• Mix together flour, baking powder and salt.
• Stir in the yogurt till the dough is too stiff for a spoon, then knead it in the bowl till it holds together well, adding more flour if necessary.
• Turn it out on a floured surface and continue kneading for about 5 minutes till the dough feels smooth and elastic.
• Form the dough into a ball and put it in an oiled bowl, covered with a towel, to rest for an hour or longer.
• Take the dough out and cut it into 10 equal pieces. Form each into a ball and press the balls flat into round discs.
• Heat a large frying pan or griddle, either seasoned cast iron or a good non-stick finish.
• Heat your oven and broiler to 500 degrees F.
• Take 1 piece of dough at a time and roll it out on a floured surface till it is about 8-10 inches across and less than 1/4 inch thick.
• Lay it on the hot griddle and cook it over a medium heat for 4-5 minutes.
• Slide a spatula under the naan and transfer it to the oven, directly onto the rack, for a minute or two, just till it finishes puffing up into a balloon and begins to color lightly on top.
• Remove naan from the oven and brush it lightly with melted butter if you like.
Tip: To reheat, wrap them in aluminum foil, in packets of 4 or 5 breads and put them in a 400 degree oven for 10-15 minutes.
