Also, people suggest salmiakki has a lot of ammonium chloride, which tastes bitter. Frankly speaking, I didn't catch any of that bitterness, instead, there are full of liquorice.
@skyblond I love licorice.. but salmiak is a bit a different kind of taste. My mom and sis love it. I sometimes do. I like a blend. But damn, yeah, I do love me some licorice. :D
And I found salmiak tasting salty though, not really bitter.
