There are actually 5 kinds of wild Alaska salmon. Here we usually call them by their colors, but they are: Chinook (Kings), Sockeye (Reds), Coho (Silvers), and Pinks or Humpies. The 5th is a chum (or dog) salmon, which while probably still nutritious, has a very soft, unappetizing texture and not a good flavor. It's used to feed dog teams a lot. You'll seldom see Chinook, even fresh or frozen, outside of Alaska or the Pacific NW. Sockeye and Coho are very popular as frozen filets or smoked. Pinks are the most often canned variety. Copper River Reds (Sockeye) are considered a delicacy. The very best fresh - imho
- are kings, esp when my DH brings one home.
Needless to say, we eat a lot of salmon.
