Postre vigilante

Vigilante is a simple Argentinian dessert consisting of a thick slice of cheese topped with a sweet, jelly-like fruit paste (dulce). Although it is usually prepared with quince or sweet potato dulce, regional varieties include goat cheese and pumpkin or cactus paste in the north, while other varieties may also employ various types of fresh and aged cheese combined with elderberry, raspberry, papaya, or bitter orange dulce.

The dish was named after a colloquial word for police officers (vigilante) who loved this simple, portable combination. A similar treat is known as Martín Fierro in Uruguay, where it's usually prepared with quince paste.
