Take a small bowl and fill it with water - set aside.
Place a stainless-steel wok or frying pan on a high heat. (Note: Do NOT use a non-stick frying pan).
Important: Wait until the pan gets very hot (almost smoking hot).
Once the pan is hot - pick up one of the naan pieces and place it - topping-side down - onto your hand. Dip your finger into the water and dab it across the back of the naan.
Then carefully place the naan onto the frying pan (water-side down). Then use your fingers to gently press the edges of the dough onto the frying pan - so that it sticks.
Then immediately flip the frying pan over - upside down. And move it across the open flames - back and forth.
Let the dough cook until you start to see bubble rise from the naan.
When you see some darkening on the bubbles, flip the frying-pan back over and set it onto a cool part of your stove. Use a spatula and carefully nudge the naan off the bottom of the frying pan.
Then use a metal utensil and briefly place it directly over the gas flames. Give it a flip - this direct contact on the flames gives a beautiful color.
Finally, gently dab a bit of the melted butter over the naan pieces! It's ready to eat - congrats!
(Note: It's perfectly normal for some of the ingredients to fall off or to char during this process! Don't feel discouraged.)
