Comments on: Ike Jime 3: Fish Killing 7 Ways The International Culinary Center's Tech 'N Stuff Blog Thu, 09 Jan 2014 18:17:16 +0000 hourly 1 By: davearnold Fri, 28 Jan 2011 14:16:40 +0000 Howdy JK,
Dave Chang just told me that the best sushi restaurant he’s ever been to (I think in Tokyo, but might have been Kyoto), did not use Ike Jime on his anago. The reason? He didn’t want such a firm eel. With many types of fish (blackfish, for instance), no-jime (or western as we call it), is generally preferred on the first day (it comes out of rigor faster, etc). I think the technique used on a particular fish is determined by:
Chef’s tastes and prejudices
Type of fish
Projected time between killing and eating
Exact texture desired
Any thoughts?

He said he would not do that on all fish and not for grilling. He mentioned that the grilled snapper was “no jime” and if I understood correct they fill a container with lots of ice and little “salt/seawater” and “slap” the fish onto the ice to kill it, then slide it into the tank for a bit.
He did not speak much english, and used a little translator pocket computer so I might be off

Thanks for a great website. So much useful information – just a great read!

I fish regularly out of Hilo, on the Big Island of Hawaii. In general I’ve been taught by my Hawaiian mother-in-law to always ice and whenever possible bleed fish as soon as they’re caught. There is a very noticeable difference (positive) in terms of the keeping quality, flavor and texture of fish that are treated that way.

Locally there has been quite a change in the way some commercial fishermen treat their catch over time. Those who actively court the Japanese buyers do take the trouble to properly kill and store their catch. Others just throw stuff in the cooler and hope for the best…

We eat a lot of the fish I catch raw or slightly marinated. I’ve noticed that different species of fish have textures which change differently over time. Some must be eaten within 24 hours (tuna, rainbow runners) and others need to wait a couple of days (snappers) before they’re not “tough” any more. For some which are relatively flavorless and more durable (hotel food), it doesn’t seem to matter so much (mahimahi, ono).

So much to learn…

Unfortunately it is trial and error. Usually, big or strong fish take longer to come out of rigor.

By: Paul Wed, 08 Dec 2010 04:35:51 +0000 Since different fish enter rigor and rejuvenate at different times, is there any way to tell the optimal time to eat after ike jime-ing them ( i.e. the striper here was best after 24 hours, where I saw somewhere else that blackfish was best after 48 hours)? Is this a trial and error thing?

By: Tom Re Mon, 14 Sep 2009 21:52:11 +0000 2 interesting articles on this…

Neither say to put wire down the spine. They say to spike the brain. “When the brain has been successfully spiked the mouth opens, the fins flair, and the tail flaps”…Gruesome!

By: Tom Re Mon, 14 Sep 2009 17:30:44 +0000 Gotcha. I also can’t help but think that the most defined results would be in a fish like a blue or a tuna although there’s a fat chance you’ll get a live tuna to Ike Jime.

the tail is left on as handle. The head is, I think, mainly for presentation purposes.

By: Mike Sun, 13 Sep 2009 13:17:32 +0000 Tom RE you dont need piano wire actually a piece of trolling wire 40# test we used to catch the stripers works.We use a piece of 100# mono leader material will work as well if fish is flat it will slide right up the spinal cord

By: Tom Re Tue, 08 Sep 2009 23:14:15 +0000 Also why not completely cut off the head and tail, bleed out, then fillet? Are they merely there for something to hold while filleting?
