The Salty Secret
Walk into any Swedish convenience store and you will find an entire shelf dedicated to licorice. Not the sweet, chewy kind sold in English-speaking markets — something sharper, darker, and chemically strange. Salmiak.
The key ingredient is ammonium chloride (NH₄Cl), a mineral compound that delivers an astringent, saline bite no amount of sugar can fully soften. In Sweden, the Netherlands, and Finland it is beloved. Everywhere else it is considered borderline inedible.
A Nation of Converts
Swedish children encounter salmiak before they can read. It shows up in school tuck shops, in grandparent candy bowls, in paper bags at Saturday markets. By adulthood the acquired taste has become a craving — a flavour hardwired into the reward circuits of a significant portion of the Nordic population.
Djungelvrål ("Jungle Roar") is perhaps the most famous example: a tiny black square dusted in ammonium chloride powder that delivers a sensory shock on contact with the tongue. It is polarising by design.
What Makes It Addictive
Researchers believe the bite of salmiak triggers a mild opioid-like response. The shock of the ammonium chloride is followed by a flood of relief, then a craving for more. It is the same loop that makes sour candy and chilli peppers compulsive for those who grow up with them.
Building Your First Licorice Box
If you have never tried Swedish licorice, start mild. Skipper's Pipes (soft, lightly salted) or Johan & Nyström's classic soft licorice are gentle entry points. Work toward Djungelvrål only after you have recalibrated your palate. Give it three tries before you decide.
