Identify how your recipe treats salmon (fillet flaky vs. mixed flaked vs. smoked/broiled), then pick the closest substitute from the table.
Use the listed ratio to match portion and cook outcome (scale down richer options like mackerel).
Match texture: drain/rinse canned salmon for less wetness; cook char/trout using the same doneness cues as salmon.
Adjust seasoning: add dill/lemon/garlic for a lighter fish vibe, or use stronger aromatics to balance mackerel’s intensity.
Finish with method-specific timing—remove from heat as soon as the center flakes easily to avoid drying.
