So we have closed this question for being to localized. I went in and edited question because it felt like the OP was being ignored due the broken english of his question. I don't really understand how we can accept questions that can deal with regional cuisines and not a question that could apply to a lot of the world, as I am sure that more than just the country of Malaysia has people that don't have access to an international market.
I do agree that the question is a little simplistic but we have other questions that are the same level IMO. I could see closing the question as off topic as hunting down ingredients isn't really what this site is about. I personally would have preferred a "what kind of rice can I use as sushi rice" question, but I feel as the too localized is a terrible precedent here.
If we are going to write off 27 million people as too localized, at what point is our cut-off? Is it 50 million? 100 million?
