01 - In a large mixing bowl, whisk together the sourdough discard, yogurt, sugar, melted butter (or oil), salt, baking powder, and baking soda until smooth and well combined.
02 - Gradually add the all-purpose flour to the wet mixture, stirring with a wooden spoon or your hands until a shaggy dough begins to form.
03 - Add warm water 1 tablespoon at a time, working it in after each addition, until the dough becomes soft and slightly tacky but holds together in a cohesive ball.
04 - Turn the dough onto a lightly floured work surface and knead gently for 2–3 minutes until the surface is smooth and elastic.
05 - Place the dough in a lightly greased bowl, cover with a damp kitchen towel, and let rest in a warm spot for 1–2 hours. The dough will puff up noticeably though it may not fully double in size.
06 - Gently punch down the dough and divide it into 8 equal portions. Roll each piece into a smooth ball and set them on a lightly floured surface.
07 - Using a rolling pin, roll each dough ball into an oval or classic teardrop shape approximately 1/4 inch thick. Keep remaining balls covered while you work to prevent drying.
08 - Heat a cast iron skillet or heavy nonstick pan over medium-high heat until the surface is very hot and a light sprinkle of water sizzles on contact.
09 - Place one rolled naan onto the hot skillet. Cook until large bubbles puff across the surface and the underside turns golden brown with charred spots, about 1–2 minutes. Flip and cook the second side for another 30–60 seconds until fully cooked through.
10 - Immediately brush the hot naan with melted butter. Sprinkle with minced garlic, fresh cilantro, or nigella seeds if desired. Repeat the cooking process with the remaining dough balls and serve warm.
