I tried these not so long ago.
They are sort of dulce de leche/licorish covered with chocolate. They melt in your mouth.
Tastful and suggary. Its crunchy yet liquidy and sticky. Its covered by chocolate very thinly, it give is a nice touch.
If you go to Argentina buy this along with Alfajores de Maizena (Sugar Cookies with dulce de leche in between) or any assorting from the brand Havanna, and this small chocolates Bocadito Marroc from the brand Fel Fort. I’ll post a picture of both soon.
