Survive may be a strong word, but how many days can you comfortably stay without it ..
I confess that in my case, maybe 4 .. max 5 days .. I need my daal chawal achaar, aaloo gosht and roti, or briyani after that .. that also home cooked, not carry out
oh and on 6th day, if its still not available, what food style would bring you closer to your desi taste .. in my case its Arabic food
I didn't care much for desi food or my mom's homecooked stuff UNTIL I started dorming. Man oh man, I would have given anything to have my mum's matar pulao and all the amazing stuff she cooks. I learnt my lesson and now cannot live without it.
