いくらの塩漬け (Ikura no Shiozuke)

A sure sign that fall has arrived: the supermarkets are full of nama sujiko (raw salmon roe sacs). You can't really eat nama sujiko as is but with a little bit of work it can be made into ikura (salmon roe). For some reason ikura no shouyu-zuke (salmon roe preserved in soy sauce) is the recipe preferred by home cooks, perhaps because it's fairly easy and keeps well. And that's how I've been preparing it for the last few years, either with my own formula of soy sauce, sake and mirin or with the little pouch of seasoning usually sold with nama sujiko.

But this time I decided to try making ikura no shio-zuke (salted salmon roe), which is the way prepared ikura is normally sold-- the bright orange roe found atop sushi and donburi. Because it must be eaten quickly and requires a few extra steps it's rarely made at home, but after studying a few recipes online I realized it's not that much more work than ikura no shouyu-zuke.

So I gave it a shot and was well-rewarded for my efforts. Salmon roe preserved in salt has a cleaner and simpler flavour than when preserved with soy sauce, and is so delicious that leftovers are not a problem-- it's likely to be eaten all up on the first day, so no worries about how long it keeps. If you can get your hands on nama sujiko then I highly recommend making ikura, as it is cheaper and fresher than any ikura you can buy in a store. The recipe is as follows (or see the step-by-step pictures of the process on my Making ikura album):

いくらの塩漬け (Ikura no shio-zuke)

You'll need one sac of nama sujiko. This is what it looks like from a Japanese supermarket: at 210 grams this one's a bit on the small side (I think the average is about 250 grams) and at 625 yen it's a good deal-- it normally costs closer to 1000 yen for a whole sac. Note the little pouch of seasoning, which is for making ikura no shouyu-zuke. If you've never prepared ikura before it's a good idea to use this seasoning as it's fool-proof, but I normally toss the pouch as it contains too many additives for my tastes.

Begin by soaking the sujiko in a bowl of very hot water. Use the hottest water you can stand (from 45 to 60C/110 to 140F) and let it soak for a few minutes. This is to temporarily toughen up the eggs so they won't break, as removing them from the sac requires a bit of rough treatment. While the roe toughens it will start to lighten in colour and turn opaque, but don't worry-- it will be a lovely translucent orange when you're done.

After a few minutes of soaking, use your hands to remove the roe from the thin membrane around the sac. Be gentle, as the roe is liable to pop if you're too rough. Once the roe is out of the sac there will still be pieces of sticky membrane and veins attached to it. It's quite tricky-- and a bit grotesque-- to remove everything, and you'll likely spend at least 20 minutes on this.

The roe is heavier than the membrane, so you can rinse out the water--along with any floaty bits of membrane--quite easily. You might also like to give the roe a good stir with your hands and run a tea strainer through the water to remove the floating pieces of membrane.   

When every last piece of membrane is removed, pour off the water and add a scant teaspoon of salt.

Mix it into the roe gently by hand. The roe's colour will start to change immediately.

Place the bowl in the fridge for half an hour to let the salt absorb. After 30 minutes the roe will be bright and translucent, but it's not quite done yet. 

Add another scant teaspoon of salt and mix it in gently.

Pour the roe into a sieve. Set the sieve into the bowl and drain the fridge for one hour, or until the roe is plump and all the liquid has drained. 

This is the finished ikura: so fat it looks ready to burst, with a beautiful bright orange colour. It is now ready to eat, or you can pour it into a clean glass jar and keep it in the fridge for up to two days. Some say it is best eaten straight away, while others say it improves after a day, but if you're like me you won't have the patience to wait.

Taste an egg before using-- if you find it too salty, soak it briefly in cold water and drain in the fridge for 15 minutes.

So what to do with it? It's great in temaki (hand rolled sushi) or on chirashi-zushi (scattered sushi); in fancy hors d'oeuvres; as a garnish for both Japanese and western dishes; or with Japanese style spaghetti. In Japan two of the most common ways to eat ikura are atop daikon oroshi (grated daikon radish) to accompany sake, and in ikuradon (a bowl of rice topped with ikura). I think I'll go with the latter this time.

Again, complete pictures of the process are in my Making ikura album on Flickr, so do check it out if you plan on making your own ikura.

I bet I could eat the whole batch...

that is so cool! I've never done this before. Will have to try. Thanks for the tips.

[JW]

thanks for the demo -- I had no idea that salt was the magic ingredient! I just wish I liked ikura more...

[Lisa (Homesick Texan)]

Oh wow! I'm now on the hunt here in NYC for some nama sujiko as I so want to try this. Beautiful!

[joanna]

salmon roe is one of the few things in japanese food that I cannot eat. I find it too much tasting too much like cod liver oil

[hikalu]

great cooking and pictures. Somehow, I've got a gut feeling that I can cook it too. A nice report.

[elarael]

Wow, excellant pictorial! I used to adore Ikura before I became vegetarian. I'll pass this on to my mom in Seattle, thanks!

[Andy]

What a phenomenal post. I just copied one of the pictures to my blog and linked it back to you. You are SUCH an inspiration! Congratulations.

[Amy]

Joan, too late! I already did.

Thanks for all the kind comments, and thanks for the link Andy!

This is good for ice cold refreshments and we need it here in OZ now.. It's hot in here:)

[Rachel]

Thanks for the demo:)
My mom's friends went fishing last fall and found roe in most of the salmons. So i make it the way you did. It was great:), made my grandpa really happy (he adores Ikuras)

[domesticshorthair]

Wow! Thank you SO much for the lesson on making ikura. It is such a favorite for me, that I have it last when I eat sushi and I consider it my dessert. I've often seen the sacs at a local Japanese market, but never knew how to make ikura. Now I do and I don't have to pay a high price for a small jar of ikura anymore!
