Doesn't have to be Korean, most countries with any coast line make good flaky sea salt. Here in Denmark, we make it on the island of Læsø, where the geography helps concentrate the sea water before it is used to make sea salt. That's the fancy expensive stuff. I use flaky sea salt from 2kg buckets I buy at a restaurant supply store. Much less expensive, works just as well.
