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 until a shaggy dough begins to form and no dry pockets remain.
03 - Add warm water 1 tablespoon at a time, kneading gently, until the dough is soft and slightly tacky but holds together in a cohesive ball.
04 - Transfer the dough to a lightly floured surface and knead 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 rise in a warm spot for 1–2 hours until puffed (it may not fully double in size).
06 - Punch down the dough gently and divide into 8 equal portions. Roll each into a smooth ball.
07 - On a lightly floured surface, roll each ball into an oval or teardrop shape approximately ¼ inch thick.
08 - Heat a cast iron skillet or nonstick pan over medium-high heat until the surface is very hot and lightly smoking.
09 - Place one rolled naan onto the hot skillet. Cook until large bubbles form across the surface and the bottom is golden brown, about 1–2 minutes.
10 - Flip the naan and cook the other side for 30–60 seconds until charred spots appear and the bread is cooked through.
11 - Remove from the pan and immediately brush with melted butter. Sprinkle with minced garlic, fresh cilantro, or nigella seeds if desired. Repeat with remaining dough portions and serve warm.
