Preheat the oven to 500 F.
Take about 3 tablespoon of warm milk in a bowl and add the saffron thread to it. Mix well and keep it aside
Divide the dough into 4 equal pieces and shape them into a ball. Let the balls rest (covered) until the oven is preheating.
Using a little flour to dust, roll each piece of dough ball into a ¼ inch thick circle. My flatbread was about 6 inches in diameter. Make sure to keep them ¼ inch thick and not to make it thin.
Keep the rolled flatbread covered with a cloth to avoid drying out.
Pick one piece of the rolled dough and flip it in your hand. Now place it on a cooling rack. The side that was touching the surface when rolling will be the top when baking.
Brush the top of the dough with the saffron milk and sprinkle the sesame seed on the surface.
Carefully place the cooling rack directly on the rack inside the oven. Let it bake for about 3 minutes. Check to see if the Khameer is evenly browned on all sides. I rotated the pan once in between the baking for even browning.
Remove the khameer from the oven and let it cool. Repeat the same with the rest of the rolled dough. I always allowed the oven to heat for about 3 to 4 minutes before placing the next flatbread.
I also used 2 cooling racks to alternate the baking, so one rack could cool to room temperature before placing the next flatbread.
Serve the Emirati Khameer at room temperature or slightly warmed with cheese or jam. I served it with some fresh local honey and it was the best thing we ate.
