Dear George
The curry gravy always stays on top of the cooker it is never refrigerated,when the kitchen staff arrive at 4:00pm ?the first thing they do is boil the gravy , switch ?on ?the tandoor ?, start pre- cooking the chicken ,lamb and defrost the prawns in boiling water chopping the coriander leaves , onions,garlic, ginger.......etc, make the rice,defrost some onion bahja in the microwave, defrost some samosa ( may be some other time i will tell in details about samosa and onion bahja )
The gravy pot ?stays on ?top of the cooker say from midnight until 4:00pm the next day i.e for 16 hours or may be 2 or 3 hours less
No fridge will take the big pot ,it is really big.
It does not finish in one day ,may be 3-4 days
During the restaurant hours of business the kitchen is very very hot it can reach up to 100 F specially if the tandoor oven is on.
This is an idea about the kitchen
Thanks
