In a bowl take the whole wheat flour, semolina, yoghurt, baking soda, oil, sesame seeds, red chilli powder, cumin seeds powder, turmeric powder, asafoetida and salt. Mix them well till you get texture like crumbs.
Now add very little water at a time and knead a tight dough.
Take a big ball from it and roll it into a big thin chapati.
Now with a cookie cutter cut it into different shapes or just cut it into squares. Prick them with the fork .
Place them in a baking tray lined with a baking sheet.
Bake them in a preheated oven at 180 deg celcius or 350 fahrenheit for about 25 min flipping them in between. The time of baking varies from oven to oven.
Remove them and cool them and serve.
Notes
Try to knead a tight dough. Add water little by little at a time.
You can also use cream instead of yoghurt.
The baking time varies from oven to oven. Hence check on it when the puris are baked.
