To activate the yeast, take the warm water in a mug. Stir in the sugar and yeast. Cover and let it sit for about 10 minutes until the mixture is covered in froth.
Sift rest of the dry ingredients: flour, salt and baking soda in a large bowl using a sieve. Whisk well.
Add in the ghee and yogurt. Start kneading the dough by adding the yeast-water mix, little by little.
If doing manually, knead well for about 10-12 minutes.
Brush the dough with oil or ghee and cover the bowl with a cling film. Put in a warm place to allow it to rise, for 2-3 hours, until it doubles in size.
Deflate the dough and knead for a minute again. Divide it into three equal portions.
Preheat the oven to its highest temperature setting. And preheat an iron skillet or tawa pan on the hob.
Roll out one portion with the help of your hands or a rolling pin. Use your fingers to make impressions all over, leaving a border by the edges.
Brush it with water/milk and sprinkle poppy seeds on top.
Place it on the preheated skillet, flat side facing down, and cook on medium heat for about 3-4 minutes.
Remove from the skillet and place it on a baking tray and broil it in the middle rack of the pre-heated oven for about 2 minutes. (That is, bake it on the grill setting.) The time taken may vary from oven to oven, so be cautious not to burn it.
Repeat the same instructions for the remaining two portions of the dough.
