Removing Aku (Harshness) from Warabi (Bracken Fern)/蕨(わらび、ワラビ)の灰汁(あく)抜き

While talking with my parents about warabi (young shoots of bracken fern), I realized that they did not know a proper way to remove aku from warabi. They said they boiled warabi in a pot of water plus baking soda for some time.
Well, recipes for removing aku (harshess) from warabi vary. Some recipes do say to boil warabi, but only for ten to twenty seconds. I, for one, do not boil warabi. I made a mistake of boiling warabi for aku removal once, and the warabi ended up being pulpy, losing all of its flavor.
両親とワラビについて話している時、両親はワラビの灰汁を抜く正しい方法を知らないことに気付きました。ワラビは重曹を入れたお湯で茹でるそうです。
ワラビの灰汁抜きの方法は色々あり、ワラビを茹でる方法もありますが、それでも10~20秒程度です。私自身はワラビは茹でません。一度、ワラビの灰汁を抜くのに茹でるという間違いを犯しましたが、ワラビは紙を食べているような食感で、風味がまったくなくなってしまいました。

Here are the warabi my father picked up today from two places.
今日、父が二か所から採ってきたワラビです。 
Much shorter and thinner than the ones I used to pick up in the Snow Country.
雪国で私が採っていたワラビよりずっと短く、細いです。

My parents like to have them with mayonnaise.
両親はマヨネーズで食べるのが好きです。
I am no big fan of warabi. Besides, the warabi here in Chiba cannot be compared with the ones in the Snow Country.
私はワラビはあまり好きではないです。それに、千葉のワラビは、雪国のワラビと比べものになりません。

  1. I have never tasted warabi.... though I know this plants grows here too because I once stumbled on internet upon an association of Korean (Swiss residents) who, among other activities, organised a trip to the forest to pick warabi!
    You have reminded me of warabi mochi... It's the only Japanese dessert I'm crazy for, especially with matcha powder. It's so astringent and I love the texture... but I also like the soybean flour traditional version.
    Though I think that nowadays it's rare to use the real warabi flour to make it....

  2. Sissi: Warabi is a spring delicacy, and just like fukinoto, seri, and other sansai, you'd feel you are missing something if you didn't have the delicacy once or twice when it's in season.

    My father says he likes warabi mochi, and I will make some warabi mochi soon, using kakakuriko (potato starch). Real warabi ko (flour) can cost 1,500 yen or higher per 100 g, and it's gray not white.
