These weird little things are another Danish treat my friend picked up in Iceland. Tyrkisk Peber Volcano translate as "Turkish Pepper Volcano." They're supposed to be hot (spicy) but on the first sample, I didn't find that true, though later I tried again and did they did have a spicy aftertaste. Meanwhile, I must mention that these are basically licorice pyramids filled with goo.
In fact, this British candy merchant describes them better than I can:
Tyrkisk Peber Volcano live up to their name in more ways than one. First, the packs contain two shapes - cone and square based "volcanoes" - which are both filled with delicious gooey "lava". Next, these are rated 3-flames, nice and hot! And last of all, this Volcano variety lives up to the name of Tyrkisk Peber itself - you will not be disappointed!
