Schwenker

Schwenker is a local term from the German state of Saarland, the Mosel Valley and big parts of Rheinland Pfalz and is used in three ways, all relating to the same grilled meat: Grilling is done over an open beech wood fire. Charcoal is sometimes used, but that is regarded as sub-standard because the beech smoke is considered to be an important part of the process. Gas-fueled grills are never used (except in commercial snack bars). Beside the Schwenker, sausages (German bratwurst and French merguez), different vegetables (such as bell peppers), Brötchen (German bread rolls, in Saarland preferably Doppelweck, see German cuisine), baguette (French type of bread) with garlic butter, potatoes and feta cheese (the latter three protected in aluminium foil) may be grilled.
