Škvarky
Čvarci is a specialty popular in Southeastern Europe, a variant of pork rinds. They are a kind of pork cracklings, with fat thermally extracted from the lard. Čvarci are mostly a rustic countryside specialty, common to the cuisines of Serbia, Bosnia, continental Croatia, Slovenia, Romania, Bulgaria and North Macedonia. They can also be found in other countries throughout Central and Eastern Europe: in Poland, Czech Republic, Slovakia, Austria, Hungary, Ukraine and Belarus. They are usually homemade, with industrial production not as pronounced. In larger cities they can be obtained on farmer markets or in supermarkets. Preparation of čvarci involves melting the lard. Lard is cut in blocks of about one inch (2.54 cm) in size and slowly fried in their own fat. Milk may be added at this point in order to obtain caramel colour. Process lasts until all fat melts away and only a kind of tough crispy pork rind remains. Onion or garlic may be added as a spice and salt is always used as a condiment. Pieces of skin may or may not be attached. In most common varieties of čvarci, some percentage of pork fat remains.
