Take all-purpose flour /whole wheat flour which ever you like. I took half whole wheat and half maida(all-purpose flour). Add oil, salt and Knead a soft dough. Keep aside.

In a big mixing bowl, add all the vegetable of your choice. And all the vegetable should be half cooked. As the rest cooking will be done while in dum.

Then add turmeric powder, red chilli powder, Biryani masala(homemade), salt and add curd and marinate the half cooked vegetables. I used 4 tbsp oil for marinating the vegetable, don't add curd for marinating. Add a little pinch of extra salt in marinate as when you add rice it will get balanced. (If you want you can use too.)

In a kadhai, add water and let it come to a boil, then add bay leaves,cloves, Black pepper corns,and one small stick of cinnamon and then add the soaked rice (soak the basmati rice for 20 minutes)

Cut two onion into long thin slices and fry them until golden brown. This will be used for garnishing the biryani.

Prepare the kadhai in which we are going to place our biryani potli. Grease the kadhai with oil and add jeera and kalonji on it and sprinkle some coriander leaves. And prepare the ingredients for assembling the Biryani.

Now dust the working area with some flour and roll out the roti. And slowly place it on the kadhai that we have prepared.

Now start assembling. First add some chopped pudina leaves, then fried onions layer, then add the marinated vegetable, and add rice layer. Sprinkle some coriander leaves and pudina leaves.

Repeat the same process. And here in the end you can drizzle keser milk on top before closing the potli. Just before starting the preparation just soak few strands of kesser in 3 tbsp milk.

Now try to bring together the excess dough like shown in the picture.

Brush the top with some oil. Then turn on the stove at slow flame. As we are cooking on dum we are going to first place a thick tawa under the kadhai and then cover the kadhai with a plate. And let it cook for roughly around 45 min.

After 45 min, remove the top plate and put a tawa. As we have to flip and cook again the top part of our potli for another 20-30 minutes. After you flip successfully, place it back at the slow gas. To cook the top part of potli.

Remove from the gas stove and remove the covered kadhai.be careful it will be hot
