Wow is hon wasabi expensive on Amazon.de Hon Wasabi is made from wasabi root. Regular tube wasabi is normally a different horseradish variant. The powdered stuff.... I would pass on that unless traveling carry-on only with liquid restrictions (and even then, I have a small stash of decent wasabi packets).

The actual wasabi root is expensive but not that expensive. It's also labor intensive to grind it from the root. We usually get hon wasabi tube from our local Japanese grocery for around $6-7/tube since we're fortunate to have styles of asian grocers (Chinese, Japanese, Vietnamese, Korean, etc). It might be something you can get from Amazon.co.jp in the future after all this or bring back from Japan. It is shelf stable until it is opened.

I will say that we/I have been more attentive to food safety recently along with actively being more easy going about food. It isn't the time for tummy aches or wasting food. My state's restaurants are delivery and take out only at the moment. If we do get take away then we are ordering two meals worth and storing the second meal & re-heating properly to reduce trips.

@LapLap Perhaps another thickener like cornstarch or arrowroot? Do people use rice flour as a thickener?

I think the thread is for virtual visits since many of us are outside Japan at the moment? I'm enjoying the start of cat X sakura season and regular sakura season on instagram.
