Wikipedia
The Kaiser roll , also called a Vienna roll (Wiener Kaisersemmel; as made by hand also: Handsemmel, Slovene: kajzerca) or a hard roll, is a typically crusty 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 outwards 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.
Semmel (derived from , wheat flour) is the common name for any kind of roll in Austria and the German state of Bavaria, equivalent to Brötchen in Northern Germany or Weck in Baden-Württemberg.
