There’s nothing higher than a recent yellowfin tuna, straight out of the water, on ice, cleaned and cooked… barely cooked!!! The Orange Chipolte sauce over the seared tuna was nearly as good because it presumably will get!!!! It actually makes for a tremendous day when you’ll be able to go offshore, catch a lovely fish and are available again to the dock and revel in it with buddies!!!!
As for cleansing any fish, a properly made, sharp fillet knife makes the work a lot simpler! take a look at the knife I exploit probably the most!
