Mix all the dry ingredients and combine well till it's mixed properly.
Take the lukewarm water in a big mixing bowl and slowly incorporate the dry ingredients into the water and mix well. It will look like a shaggy dough at this point. Don’t attempt to knead it at this point. Simply cover the bowl and keep it aside for 10 minutes.
Knead the dough on a clean kitchen counter using the oil and making your hands a bit moist when it's too sticky to handle. Knead for 10-12 minutes by using the stretch and fold method into a smooth, soft and pliable dough.
Place the dough in a well oiled bowl and cover the bowl with a cling wrap and keep it in a warm place for the dough to double in size.
Once the dough is doubled, gently punch the dough and remove the air bubbles. Knead again for a minute or two. Roll the dough into a rectangle and fold it tightly like a log and seal the edges well.
Place the rolled dough in a well oiled bread tin, apply some oil on the top of the log and allow it to almost double or till the dough almost reaches the brim of the tin.
Preheat the oven at 180 degree celsius for 10 minutes and bake the bread for 40 minutes till the crust is almost golden in colour. Remove from oven and apply butter on the crust and bake for 5 more minutes or so at 190-200 degree celsius.
Remove the bread from the oven and apply butter on top. Gently take the bread out of the tin and allow it to cool on a wire rack till it's fully cooled. Wait for atleast 2-3 hours before slicing.
Slice into meat slices and serve.
