Why this matters
The outside of a protein tells you about browning, while a thermometer tells you about the center. Those are different questions. Thickness and starting temperature change cooking time, so the clock is only an estimate. Clean hands, separate tools, prompt chilling, and measured internal temperatures protect the meal before, during, and after the pan is hot.
How to do it
Pick up seafood near the end of shopping, pack it with cold items, and refrigerate promptly. Use an insulated bag for a long or hot trip home.
What to look, hear, or feel for
Fresh seafood should be cold, with a clean mild aroma rather than a strong sour or ammonia smell. Packaging should not leak or bulge.
When something goes wrong
When its time or temperature history is uncertain, discard it. Cooking cannot reliably correct spoilage or every toxin produced during poor storage.
Try it in a real meal
Use a clean, accurate food thermometer and current official guidance whenever animal proteins or leftovers are involved.
