You can also use Chicken Kuzhambu or Mutton Kuzhambu tomake Kothu Parotta. Kothu Parotta is my mom's favorite food too, few months back I made this kothu parottafor our Sunday Lunch and I shared this pictures with my Mom on whatsapp
As I never able to flatten the dough to thin film Because I did not give enough resting time though the parottas were soft but not flaky and couldn't make layered ones
