Reddit mentions of Fazer Tyrkisk Peber Original Hot Salmiak & Pepper Candy (150g)

Looking at the Amazon US site, if you're not familiar with the different types of Finnish salmiakki, there's a 4-pack that would let you try different types:4 Boxes X 38g of Fazer Super Salmiakki Mix ((2) salmiakki - (1) super salmiakki - (1) pantteri) Original Finnish Salty Licorice

The "Fazer Ässä Salmiakki" is a sweet salmiakki, not as bitter if you don't like that.

Also great are the "Fazer Tyrkisk Peber"
I find them addictive, and they have a great burning sensation from the ammonium chloride (Latin sal ammoniacus, from which the name salmiakki comes)

Be warned though, it's an acquired taste and very different from North American candies:
Americans Try Finnish Candy: Tyrkisk Peber Turkinpippuri Salmiakki

If you're ever in Finland, definitely try Apteekin salmiakki, and the Fazer salmiakki ice-cream!

You can find this in Northern Europe, Germany and Turkey. I've seen some in Finland and Denmark. They go by other names. This picture is the Danish one. It's essentially Turkish pepper aka a kind of licorice. You might have a better chance with the English name. FAZER is a Finnish company.
