Never tried it, but apparently it's not that good. Like, super dry, and very basic taste.

I dunno how they make it in other countries, but I can confirm that a well-made German Baumkuchen, coated with chocolate to keep the dough from drying out, is simply delicious. It even got so popular in Japan that they have it in most supermarkets (baumukuhen / バウムクーヘン).

They are not dry if they are made properly and eaten straight away. The stuff we can get in the stores is of variable quality (or at least variable storage conditions).

That said, it’s popular cuisine, from regions that were historically not that wealthy. It’s a bit rustic, but there is some beauty in its simplicity.

Opposite experience. The versions I've tasted were not dry (unless left out for too long), had a sort of melt-in-your-mouth texture, was sweet, had a specific taste that's hard to name (eggnog?).

Yeah, it looks like a fun gimmick but it's basically a butter biscuit with a bit of rum and liqueur, which does most of the heavy lifting there.

Can confirm; looks great but I was disappointed while eating it.
