Dutch double-salt licorice in Broward?
Did you try world market? I know they have candy from around the world.
There's a European Grocery in Hollywood but they are more Eastern European. I doubt they have them but they may be able to point you in the right direction.
Nick, looks like Sweets from Heaven in Boca has double salt licorice. The brand name is not listed on the site.
World market in Pembroke Pines has another brand listed on their site called Katjes who has salted fish licorice. They may have more brands in store.
