Choosing the right salmon is paramount for maximum flavor and high omega-3 content. Always buy wild-caught salmon. King salmon is available in early summer, then, in late summer, you’ll find sockeye and then Coho salmon. Purchasing fish in its peak season is a good way to get it for an affordable price. Look for fillets that are uniform in thickness, this will ensure even cooking. Bright and tight flesh without gapping is a good sign of freshness.
