Which is actually fresh water fish fermented with rice and Pangi(some kind of fruit to kill of the fishy smell)
It's best when you eat it with rice without any other dishes.
Everytime when I reached home to have dinner with my dad, i would open my jar filled with my dad would back away to avoid the smell.
For him, it's disgusting because it smells and looks like rotting fish in a jar(to me it smells like cheese).
When I first saw it a few years ago, I didn't like the idea of eating it(same how like my father feels like right now). It was funny to remember back that the reason I started eating that 'thing' was to challenge myself as being so-called a Kadazan kid since most of my relatives on my mother's side likes to eat it.
From fear factor... it somehow turns to my personal delicacy at home. Gosh, my mouth just water just to imagine it when I'm really hungry.
Bosou in a jar
Plus, there's nothing better than a piece of 'bosou' for dinner after a day of hard work. Sooner or later, I need to learn how to make one instead of depending on my parents to export it from Sabah. It's really frustrating to see when there's only 1 piece of fish left in the jar and there's a long way to go before you can go back to hometown(which is only once a year!).
