Houska
Houska is a traditional bread roll baked and consumed in the Czech Republic. Typical ingredients include wheat flour , water, yeast and salt. They are topped with poppy seeds, caraway seeds, linseeds or sea salt. Rohlík is another form, similar or identical in ingredients, production, taste, size and price. A 2002 article in the Chicago Tribune published a recipe for a sweet variant, a Christmas season special variant called "vánočka". It is a lightly sweetened, traditional bread roll containing a significant amount of sugar, eggs and cream, occasionally raisins, and may be covered in poppy seeds or almonds.
