01 - In a small bowl, combine warm water and sugar. Sprinkle yeast over the surface and let it stand for 10 minutes until frothy.
02 - Whisk together flour, salt, baking powder, and baking soda in a large mixing bowl.
03 - Stir the yeast mixture, yogurt, milk, and 2 tablespoons melted ghee into the dry ingredients to form a soft dough.
04 - Knead the dough on a lightly floured surface for 5 to 7 minutes until smooth and elastic.
05 - Place the dough in a lightly greased bowl, cover, and allow it to rise in a warm place for 1 hour or until doubled in size.
06 - Punch down the dough, divide into 8 equal pieces, then roll each into a ball and flatten into an oval or teardrop shape about 1/4 inch thick.
07 - Combine minced garlic and chopped cilantro with 1 tablespoon melted ghee.
08 - Brush each flattened piece with the garlic-cilantro ghee, then sprinkle with nigella seeds.
09 - Heat a heavy skillet or tawa over medium-high. Place naan on the hot surface, cover, and cook 1 to 2 minutes until bubbles form. Flip and cook the other side for 1 to 2 minutes until golden spots appear.
10 - Brush cooked naan with extra melted ghee and serve warm.
