FIGURE 4.36 The Central Europe subregion. (A) Gyula sausage is cured in a smokehouse in Gyula, Hungary, which enjoys “Protected Geographical Indication,” or PGI. This means that, within the European Union, only sausages from the town of Gyula and those that are made in a certain way may be labeled “Gyula.” A huge variety of sausage is produced in Hungary, but only certain celebrated varieties qualify for the PGI protection. 4.36a Courtesy Ferenc Isza/AFP/Getty Images
