My aunty introduced this to me when I was still at primary/secondary school i cannot exactly recall. It has become one of my fav since then.
Aunty's version is more complicated that she adds this and that. Mine is simpler. As I cook this on my own, I discover a few things:
1. It is much better to use butter instead of cooking oil.
2. Adding some cooking oil to boil the pasta is a myth.
3. It tastes better when you add in anything cheezy to your pasta sauce. In my case tonight, i just put some slices of cheezy sausage.
