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, stirring with a wooden spoon or your hands until a shaggy, rough dough forms and the flour is mostly absorbed.
03 - Add warm water one tablespoon at a time, working it in after each addition, until the dough becomes soft, pliable, and slightly tacky but holds together in a cohesive ball.
04 - Turn the dough out onto a lightly floured surface and knead gently for 2–3 minutes until the surface is smooth and elastic. Avoid overworking.
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 but may not fully double.
06 - Punch down the dough gently and divide into 8 equal pieces. Roll each piece into a smooth ball between your palms.
07 - On a lightly floured surface, roll each dough ball into an oval or classic teardrop shape approximately 1/4 inch thick.
08 - Place a cast iron skillet or nonstick pan over medium-high heat and let it get thoroughly hot until a drop of water sizzles on contact.
09 - Lay one rolled naan onto the hot skillet. Cook until large bubbles puff across the surface and the underside is deeply golden, about 1–2 minutes. Flip and cook the other side for 30–60 seconds until charred spots appear.
10 - Immediately brush the hot naan with melted butter. Sprinkle with minced garlic, fresh cilantro, or nigella seeds if desired. Repeat with remaining dough balls and serve warm.
