Tlačenka

Tlačenka is the Czech and Slovak variety of head cheese similar to Polish salceson. Czech light-colored tlačenka is made in a number of types. It is generally bonded with brawn—thick pigskin and hock/trotters broth—with various combinations of meat cutoffs , offal (tongue, heart, liver) and fat with seasoning (salt and various combinations of spices such as marjoram, garlic, caraway, pepper, cloves, and allspice). Another version, dark-colored tlačenka, is made with added blood. It is served with raw onions, rye bread, vinegar, mustard or smoked sausages.
