Hi! As a South Indian and knowing something about how commissary kitchens work and having studied the NRI market base, I would strongly advise you to pivot.
You cannot compete with packaged foods wrt price point. You must also have something unique with no competitors. This market is too crowded. You had me at rasam and buttermilk..it’s because of the radar kinship, I want you to succeed.
If you are interested, I can help with pivot ideas but I honestly don’t think you can hit it at this market base with that price tag.
