Dear Debra,
Swedish salty licorice is definitely an acquired taste! Salty licorice uses salmiak which is ammonium chloride, to get that special sharp flavor. It is a key ingredient in Nordic salty licorice.
In a January 13, 2017 article from Saveur magazine the author, Andrew Richdale reflects on his first taste of salty licorice - "The first time I sampled salmiak, a salt licorice flavor found across Scandinavia, I spit it out on a Copenhagen street corner. It wasn't that this powerful little pastille was bad. It's just that my taste buds had never quite been lit up that way: smacked with a layer of sharp and sour salt dust, then soothed by something bitter and caramel-sweet. It felt simultaneously fascinating and...abusive? Or at least odd, like a knocked funny bone. It wasn't until the second or third try that my confusion turned to appreciation."
I will be in contact.
Best regards,
Anne Marie
