In a large mixing bowl, combine your flour, salt (if using it) and yogurt. Mix well, until combined. Then, use your hands to form a large ball of dough.
Lightly flour a wooden or kitchen surface. Sprinkle a little extra flour on top of the ball of dough, before transferring it to the floured surface. Flatten into a circular shape and divide into 8 even portions. Flatten each portion into a rectangular shape (like a classic Naan bread).
Heat a non-stick saucepan or Tawa on medium heat. When hot, place flattened dough and cook for 3 minutes, before flipping and cooking a further 2 minutes. Repeat until all the naan bread is cooked.
Melt the butter and add the finely grated garlic and stir
lightly brush the tops of each naan bread with melted garlic butter and sprinkle with nigella seeds and chopped coriander to serve
