She believed it was smashed avocado.

她以為是酪梨泥。

We knew, or at least we thought, it was wasabi.

我們知道，應該說我們以為它是哇沙比。

But many, many years later, I have come to learn that, technically, we could've both been wrong.

但在好多好多年以後，我了解到我們可能都錯了。

Yeah, it turns out [that] the spicy green paste you get in sushi restaurants isn't actually wasabi at all.

沒錯，事實上壽司店裡的綠色辣醬不完全是哇沙比。

It's horseradish and green food dye.

而是辣根和綠色色素。

Real wasabi, Japanese wasabi, is actually kind of rare and expensive, even in Japan.

真正的哇沙比，日式哇沙比甚至在日本都是非常稀有又昂貴的。

So horseradish and wasabi are part of the same produce family.

辣根和哇沙比都是從同個家族出來的。

Brasicatha... brasikatuh... brazzer... Jack, just put the word on the screen. [Brassicaceaea]

Brasaca-brasacaha-brazzer...Jack，直接把這個字打在畫面上吧！

Think of them more as cousins than siblings.

把他們想成表兄弟而不是親兄弟。

With one cousin being way more fussy to grow than the other.

只是其中一個表兄弟比另一個難伺候。

Given I have neglected every plant child I've taken on, I am turning to Esme Atkinson for advice.

因為我幾乎都沒在管所有我照顧過的植栽所以我決定問問 Esme Atkinson 的意見。

She's from Shima Wasabi, Australia's largest commercial wasabi crop.

她是來自 Shima Wasabi，澳洲最大的哇沙比公司。

So Esme, why is wasabi so hard to grow outside of Japan?

好，Esme ，我想問說為什麼哇沙比這麼難在日本以外的地區生存？

Wasabi is very prone to disease.

哇沙比很容易得病。

It needs clean air, it needs pure water, and it needs a cool climate.

它需要乾淨的空氣、純淨的水、還有涼爽的氣候。

And it can take 18 months to grow.

它需要十八個月生長。

Did we mention it was fussy?

我們剛不是有說它很難搞嗎？

Now Esme, I am somewhat of a committed plant mother myself.

好，Esme 我其實是個非常熱衷於照顧植栽的人。

If I want to grow wasabi at home, what can I do?

如果我想在家自己種哇沙比的話我能做什麼？

Is there a list? Some tips?

有清單嗎？一些小訣竅？

Can't really share any secrets, other to say, you would struggle to grow it yourself.

我不太方便講出任何秘笈，只能說自己種的話你絕對會遇到很多難題。

Ahhh, so you've got a secret locked away there.

噢！你有些秘密故意不說喔！

So, really, what are we missing out on that?

所以說真的，我們錯過了什麼？

I mean, they look the same, surely they must taste the same.

他們長得一樣不代表它們嚐起來一樣啊？

The flavor's certainly different.

味道當然不一樣。

Wasabi is a much sweeter flavor.

哇沙比的味道比較甜。

It's quite delicate—you still get the heat, but it dissipates quite quickly.

你還是會覺得辣但它很快就消散掉了。

Armed with the knowledge that, until this point, my life had basically been a lie,

具備了這個知識，讓我發現原來我的人生到目前為止都是謊言。

and my entire sushi train experience quite possibly a load of fake news,

我所有吃列車壽司的經驗中好像都是一堆假消息。

I had to double check Esme's claims, and there was really only one way to do it.

我再次確認了 Esme 的一番言論正不正確，其實只有一種可行方法。
