I was at the grocery store late last night, trying to pick up for dinner today, and the yellowfin tuna steaks looked alright. I usually do not buy tuna from the grocery store because I like to indulge in high-quality seared tuna at restaurants or raw in sushi. However, I was really tired, and the price was right. Now I am questioning my decision. I know that it's pointless to cook a tuna steak to "well-done", but how do I know that the tuna from the grocery store is fresh enough to sear safely? It says "previously frozen" on the package; does that mean it's any more or less fresh? What would be the best way to cook this piece of fish and how should I flavor it?
Am I just overthinking this? Any ideas are much appreciated!
