Shelf Life: Up to 72 hours once thawed.

Keta salmon are one of the more firm salmon varieties, so these fillets stand up well to marinating and grilling. If you have difficulty with salmon coming apart on the grill, this is the best choice for you. Because they’re also a mild variety, they’re best paired with milder ingredients that won’t overwhelm them.
Try combining keta salmon with flavors like garlic, asparagus, sweet rice wine (aka mirin), chervil, chives, cream, lemon, lime, dill, and (of course) butter. Lentils and specialty rice are both great choices for salmon side dishes.
