Take milk in a mixing bowl, add in salt, sugar, baking soda, 1 tablespoon of oil, chopped coriander leaves and mix well. Add in flour and knead into a soft dough. If you want add more flour. Now drizzle the remaining 1 tablespoon of oil over the dough and knead it one time. Cover and let it rest for 30 mins.
Dust the work surface generously, punch a little dough and roll into circles. Now use your hands to elongate the circle, so it forms into a traditional naan bread shape.
Heat a tawa with handles. Now dip your fingers in water and spread water on top of the naan bread. Once you have applied water, flip the wet side on hot tawa, as soon as you drop it, small bubbles will appear.
Don't cook it too long at this point, if you cook long then the naan will get cooked and leave the pan, so you cannot flip it over.
Once you see small bubbles, flip the tawa and show the top side over the open flame. Show it on all side, you will see some black spots on the naan.
Now apply some butter generously on top of the naan. Remove the naan to a plate. Serve hot with your favorite curry.
