Fantastic, thanks for your help. The battered cod sounds delicious also!
You can also get frozen edamame and all manner of other Japanese and Korean goodies at the Yumihana supermarket just off Bahnhofstrasse (Hbf end) in ZH:
I've seen them recently at the Manor in Vevey, but they are also available from a lot of smaller asian grocery stores.
Just saw some in the Migros at Schwamendingerplatz yesterday.
They are in the freezer section under the "Farmer's Best" brand. At 2.90 CHF for 240 g, it's a bit steep but still hits the spot.
So happy I found this thread, this is exactly what I was looking for! I only ever knew the ones at Jelmoli, but the price was just slightly ridiculous...
You can buy them at Migros!
Or you can grow soybeans yourself, if you have a garden, as we do, now we have a ton of our own organic Edamame in the freezer!!
