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
Marinate in the refrigerator in a food-safe container. Reserve a clean portion before it touches raw meat if you want sauce for serving.
What to look, hear, or feel for
Used marinade is considered contaminated even if it smells fine. A brush that touches raw meat belongs in the raw zone.
When something goes wrong
If you must reuse marinade, boil it according to food-safety guidance before serving; a fresh reserved portion usually tastes better and is simpler.
Try it in a real meal
Use a clean, accurate food thermometer and current official guidance whenever animal proteins or leftovers are involved.
