Sashimi

Masaharu Morimoto's cooking demo in Aspen was exactly that: a demonstration. To be more specific, it was a mind-blowing demonstration of how stupefyingly skilled he is in the kitchen.

The Iron Chef began by making a fried fish cake noodle soup, first puréeing white fish with egg whites, potato starch, and soy, then piping the tacky, moist mousse into simmering fish broth to form udon-like noodles, which were finished with a flash-fry in vegetable oil.

But the real show began when Morimoto pulled out his mad Japanese knife techniques to create the most stunning sashimi platter that I've ever seen. Read more about it after the jump.

After seeking out sushi-grade tuna to make my own spicy tuna poke, I became curious as to what exactly constitutes sushi- or sashimi-grade fish.

The terms "sushi-grade" and "sashimi-grade" were created to ensure certain types of seafood can be consumed in raw form — but it turns out that they're more marketing terms than anything else. There are no clear health parameters enforced by the Food and Drug Administration or any other food agency that seafood must pass in order to be labeled sushi- or sashimi-grade. The FDA does maintain that all fish eaten raw must be frozen first.

The moral of the story? When it comes to eating raw fish, you're at the mercy of the person preparing it. Make sure you're aware of the freezing conditions that the fish have been subject to: fish intended to be eaten raw should either be frozen for seven days at -4 degrees Fahrenheit, or flash frozen for 15 hours at -31 degrees. In addition, look out for any warning signs of less-than-fresh seafood, like pearly rainbow or yellowish discolorations, dull flesh, or a fishy smell.
