This is an Elephant Apple a very regular and liked food item with many health benefits used in our Assamese kitchens.Being from north i had never come across this fruit until i got married... since the time i first tasted it i fell in love with this one.It is called Ou tenga (pronounced O ,tenga means sour).Its outer covering is hard and you need to be very careful while cutting it as the inside pulp is slippery in nature.We consume it in cooked form when the fruit is not too young or too ripe.It is considered as a liver and heart tonic and anti diabetic....it is known to have a cooling effect on the body .After cutting it into small pieces(seeds are discarded ) we prefer to pressure cook it by adding some water to it....it is very acidic in nature.Once boiled some musturd seeds are spluttered in a wok or kadhahi and the boil mix is added ,later a pinch of turmeric and salt is added.....to make it more interesting fried fish can be added which is the most preferred choice out here.Its great specially if you are experiencing a very hot day .Tenga is served as the last dish (with the rice) i.e. once you are done with eating all the other items served.When kids are unwell and refuse to eat anything i always make this preparation because just one bite of tenga and rice mix is enough to stimulate their appetite.
