The Kaiser roll (German: Kaiserbrötchen [ˈkaɪzɐˌbʁøːtçn̩] ⓘ; "Emperor roll"; Slovene: kajzerica; Polish: kajzerka; Hungarian: császárzsemle), also called a Vienna roll (Wiener Kaisersemmel), a hard roll or, if made by hand, also Handsemmel, is a typically round bread roll, originally from Austria. It is made from white flour, yeast, malt, water and salt, with the top side usually divided in a symmetric pattern of five segments, separated by curved superficial cuts radiating from the centre outward or folded in a series of overlapping lobes resembling a crown. The crisp Kaisersemmel is a traditional Austrian food officially approved by the Federal Ministry of Agriculture.
