this is one of the unsung heroines of bengali cuisine
it is simple and makes bland-and-tasty a non paradox
the
gourd needs to be grated or shredded first
and then steamed
then in a little
oil (very little and preferrably mustard oil)
fry
boris (dried pulse cakes. another bengali innovations)
keep aside
add
cumin seeds and
bayleaf to the oil, and then ad
d the steamed gourd.
after a while add
ginger paste cumin paste and
corriander paste 
mixing the ingredients well cook for a while
add
salt as needed a pinch of
turmericand water if need
the trick is not to over-cook as it may turn the dish sour
lastly decorate with the crushed boris that was fried in the begining
boris can be replaced with fried shrimps
{boris are sunbaked cakes made of dal or lentils
first the the grind the dals ( and this can be made of various kinds of dals)
and made into a semi-liquid paste. these are placed into the a fine masline in the shape of small cakes and the cloth is hung out in the sun to dry. these days boris-- nicelyl packed can be bought from shops}
