Sift the flour, sugar and yeast into a bowl and add the salt, yoghurt, ghee, water, and milk to the bowl.
Bring it together to make a rough dough ball.
Knead on a lightly floured surface for 5-10 minutes until smooth. You can do this with a dough hook in a stand mixer, and it will take 4-5 minutes.
Place in a clean covered bowl and allow to sit for an hour or until the dough has doubled in size.
Heat your oven as hot as it will go (use fan mode if you have one) and place a heavy baking tray or, even better, a pizza stone or steel in there to heat up.
Turn the dough out onto a lightly floured surface and knock back again.
Cut the dough into 8 even balls and roll into naan bread shapes around 5-7mm (around ΒΌ")thick.
Throw the naan into the oven onto the heated baking tray or pizza steel and cook for 3-4 minutes.
If you have a blow torch, use it to blister the top of the flatbreads and then close the oven and cook for 90 seconds.
Serve hot, brushed with lots of ghee and coriander!
