A Brush of Romantic Pink - Mentaiko Scallion and Sesame Seeds Onigiri

Here's my confession. At first I was imagining rice balls with chunks of mentaiko throughout, like clear white colored rice and red chunky mentaiko color contrast. Little did I know that once I removed the mentaiko roe from the membrane, there's no way I can keep these little roes intact.


So I ended up with mini roes scattered throughout the rice grains, thus the romantic pink hue everywhere. Definitely not what I have in mind, but with such pretty tone in the end, not bad actually.

Ingredients (about 4 servings)?

  • 60 grams mentaiko
  • 4 portions cooked white rice
  • 1 stalk scallion
  • 1 large nori sheet
  • 1 tablespoon white sesame oil
  • 1 tablespoon toasted white sesame seeds


How?

Precook some white rice for this recipe, preferably use bit less water than usual to get slightly drier bouncier grains in the end. You can use the rice while still a bit warm, or even overnight rice that's been stored in the fridge. Just remember to bring up the temperature a little before shaping into onigiri. 


Remove the mentaiko from its membrane.

Transfer the mentaiko roes to a bowl. Destem and chop the scallion. We will only use the green section for this recipe. Add that to the bowl too, about 6 tablespoons. Also tear one big nori sheet into smaller pieces and add to the bowl. Lastly, add 1 tablespoon of toasted white sesame seeds and drizzle 1 tablespoon of white sesame oil too.

Fold in about 4 servings of rice and gently mix till evenly blended. Roughly mark four equal portions.

Take each portion and shape into onigiri, let it be round or triangle, whichever shapes are good. You can dip some drinkable water to your palms before working with the rice to prevent sticking. However, the most fool-proof way to do it is laying down a sheet of cling foil, scoop the rice mixture on top, grab the cling foil edges and tighten up, making the mixture into rice balls.


You might want to use a new sheet of cling foil for each rice balls. Also notice that I didn't put any salt to the list of ingredients? Mentaiko can be very salty so just by itself, the flavor should be salty enough.

Have you found out that this time we are not using the nori sheet to "wrap" the rice balls, instead we torn it into little pieces and mixed together with the rice. However, I suppose if you would like to keep the nori sheet on the outside, to wrap the rice ball, that should work too.

Just that the texture can be a little bit different. If using nori sheet as a wrap, usually the nori sheet sould still be crispy if being served right away. On the other hand, nori sheet as part of the mixing ingredient, it'll turn soft with almost unnoticeable texture. But that nori aroma will be evenly permeating the rice grains throughout.


So I guess in the end it's up to you regarding where to use the nori sheet. I do find it fun and a nice change once a while by using the nori sheet as part of the mix-together element though.

Baby Sardines in Japanese Sweetened Soy Sauce いりこの佃煮

What I meant by baby sardine is the dried anchovy, also called iriko (いりこ) in Japanese. Not the much more delicate little white fish shirasu (しらす). You can find the dried anchovies in the supermarket usually around kombu, seaweed, or other dried seafood ingredients.


While in Taiwanese cuisine, dried baby sardines often used in stir-fry or chili sauce, I've also made congee with dried baby sardines, upgrading that umami flavor all around. And of course the classic Japanese tsukudani (佃煮) is one other great way for such ingredient.

Ingredients?

  • 1 loosely packed cup dried baby sardines 丁香魚乾
  • 2 tablespoons soy sauce
  • 2 tablespoons mirin
  • 1 tablespoon rice wine
  • 2 tablespoons water
  • 1 tablespoon granulated sugar
  • 1 tablespoon toasted white sesame seeds


How? 

Usually the dried anchovies are stored in the freezer, at least that's what I do. So if that's the case, there's no need to defrost the anchovies the night before. Just use it straight from the freezer. Or if you happen to just bought the room temperature dried anchovies, use as it is too.


Right before cooking, quickly rinse the dried anchovies then pat dry with paper towel. Use a medium pot and add in the prepped anchovies. Switch to medium low heat to dry-roasting the fish for a short moment.

Still using medium low heat, pour in 2 tablespoons of soy sauce, 2 tablespoons of mirin, 1 tablespoon of rice wine, 2 tablespoons of water, and add 1 tablespoon of sugar. Slowly cook till all the sugar has been melted.


Adding Japanese seasonings to dried anchovies tsukudani style

Continue to cook till the sauce has been reduced, almost to a sticky consistency in the end. Mine took about 10 minutes.

Towards the end, sprinkle some toasted white sesame seeds. You can serve as it is. For unfinished portion, simple store in the fridge. Serve the unfinished portion under room temperature later on and don't attempt to reheat the anchovies again.

It's sweet and savory at the same time, which can be a great little side dish for Japanese style breakfast, maybe serve together with congee too. I actually used it as a little flavor swap for curry rice. A little goes a long way. In fact, if the portion is too big, the somewhat sticky seasonings can be a bit overwhelming. Just a spoonful or two for each serving of main meal will do.
