I live in Subang Jaya, Malaysia.
surprisingly, it’s easy to find korean ingredients here in KL. any Jaya Jusco outlet especially in Sunway Pyramid (for Subang Jaya, Bandar Sunway & Kelana Jaya area), Midvalley Megamall (Bangsar, Petaling Jaya area) One Utama & Ikano Center (Bandar Utama, Damansara area). the words (in bracket) are major cities that have Korean residence.
Jaya Jusco has an Asian section most items are imported from the original countries. they also put up labels in english so that muslims can read to be sure of the ‘halal’ness. read carefully & don’t confuse with Japanese products.
Bandar Sunway & Subang Jaya have a lot of foreign students (including Korean) living here, so it’s easy to buy a packet of ramyun even from a small grocery shop like Parkway & Herbs n Food. SS15 Subang Jaya is the easiest place to find Korean ingredients except rice cakes (for cooking ddukbokki)
Hope this helps. Happy cooking!
