• Bloom yeast: Mix yeast with warm water and sugar in a small bowl. Cover with cling wrap, leave for 10 minutes until foamy.
• Egg and milk: Whisk milk and egg together.
• Flour: Sift flour and salt into a separate bowl.
• Add wet ingredients: Make a well in the flour, add yeast mixture, and butter and egg mixture. Mix together with a spatula. Once the flour is mostly incorporated, switch to your hands and bring it together into a ball. No kneading is required.
• Proof 1: Cover the bowl with cling-wrap, then leave in a warm place for 1 – 1.5 hrs until it doubles in size.
• Cut into 6 pieces: Place the dough on a lightly floured surface. Cut into 6 equal pieces, then shape into balls into spheres with a smooth surface by stretching the surface and tucking it under.
• Proof 2: Place balls on a lightly-floured tray or plate. Sprinkle lightly with flour, cover loosely with a lightweight tea towel. Put in a warm place to rise for 15 minutes until it increases in size by about 50%.
• Roll out: Place a round on a lightly-floured work surface, flatten with your hand. Roll out into 3 – 4mm / 0.12 – 0.16" thick rounds (about 16cm / 6.5" wide).
• Heat skillet: Rub a cast iron skillet with a very light coat of oil using ½ teaspoon oil on a paper towel. Set over high heat until you see wisps of smoke.
• Cook naan: Place a naan dough in the skillet and cook for 1 to 1 ½ minutes until the underside is deep golden / slightly charred – the surface should get bubbly. Flip then cook the other side for 1 minute until the bubbles become deep golden brown.
• Cook remaining naan: Remove, set aside, and repeat with remaining naan, taking care to regulate the heat of the skillet so it doesn't get too hot.
• Finishing: Brush freshly cooked naan with melted butter or ghee (or garlic butter, Note 5). Sprinkle with nigella seeds and coriander. Serve hot!

Cheese Naan

• Roll out a naan per above directions. Brush with plain butter or garlic butter. Place a mound of cheese in the middle – about ¼ cup, lightly-packed. Bundle it up, money bag-style, then twist to seal.
• Turn upside down so the smooth side is up. Roll out to 6-7mm / ¼" thick rounds.
• Heat a well-seasoned cast iron skillet preheated over high heat, but not until the skillet is smoking. Cook naan for around 1 ½ minutes on the first side until golden – it will puff up! Turn and cook the other side for around 45 seconds.
