Sautés Poivre Noir Albacore et le rôti Anaheim Piment sur Gratin de Fenouil Pommes de Terre Yukon Gold!
Yellowtail tuna is usually called ahi on American menus. Even Japanese sushi restaurants use the work ahi on menus in America. Ahi is Hawaiian for yellowfin tuna. For a French gratin style entree, the name ahi would be a poor choice. French fusion chefs use the word ahi, but classic French chefs usually call yellowfin tuna by the name albacore.
Because of the strong lobby of Japanese fishermen and the sushi industry, yellowfin tuna always seems so escape unsustainable seafood classification. Yellowfin tuna has been steadily declining in numbers, like all tuna species. The reality is yellowfin tuna is low in numbers. Responsible chefs realize this and they do not use yellowfin tuna as bait to capture customers. Just like Atlantic cod, yellowfin tuna seems to get the same respect. Many consumers demand yellowfin tuna with no regard for the extinction of the species. Some people are deranged enough to think about celebrating over eating eating the last yellowfin tuna steak on earth. That same attitude sent Atlantic cod into extinction.
Self control helps the sustainable seafood cause. I can count how many times that I have eaten yellowfin tuna during the last five years on one hand. Today's yellowfin tuna recipe will probably be the last one posted in this food site. I also stopped posting black tip shark recipes when they become low in numbers. Supporting seafood sustainability means taking action. I have posted links to seafood sustainability site on the link page and seafood page in this site's index. Always check the sustainability status before making any seafood purchase.
Today's yellowfin tuna entree is a modern comfort food recipe. The entree is cooked in two stages, so the tuna is still medium rare and juicy. A gratin does not need to be heavily browned to be called a gratin. A few golden brown highlights are enough for certain gratin applications. Many kinds of cheese become vile and bitter when they are heavily browned. The character of the cheese has a lot to do with how light or dark a gratin should be.
The market had some very nice looking anaheim peppers for sale. Anaheim peppers are spicier than a poblano pepper and some can be as hot as a serrano pepper. Most anaheim peppers are fairly mild. Anaheim pepper has a rich crisp green chile flavor. The flame roasted Anaheim pepper adds some zest and lightens the overall feel of this gratin entree.
