Is this salmon (sake) furikake? Or is it salmon (sake) flakes? Or maybe it's even salmon soboro. Whatever you call it, it's finely flaked salmon that you can sprinkle onto plain rice, use as an onigiri filling, or on ochazuke. You could fold it into egg for a salmon omelette, on boiled vegetables...whatever your imagination can come up with.

Salmon flakes are often sold in jars that cost around $8 for about 150g. You can make it yourself for less than $3, depending on how expensive the salmon is. You can be even more frugal and use the little bits that are stuck on the bones when you filet a whole salmon. This is probably how fish soboro or flakes or furikake was invented in the first place.

Salted salmon, called shiozake or shiojake （塩鮭）, is so ubiquitous in Japan that when people just talk about "salmon" (sake or shake) they are usually referring to the salted kind rather than the raw kind (which is specifically called namazake（生鮭）). Salted salmon is a staple ingredient of bento, used as an onigiri rice ball filling, flaked on top of or mixed into rice, or just grilled.

Salted salmon is cheap and easily available in Japan, but not so outside of Japan. So I've been making it myself for some time now, and it's quite easy. All you need is a typical refrigerator that has low humidity. (If yours doesn't have excess condensation in it, and old leafy vegetables get dessicated in the corner of your vegetable bin, then it's ideal.)
