Though probably today the most commonly known and used are store-bought packages of dried yeast, there are several other different kinds. The recipes that follow show two examples of different ways to make yeast--dry yeast cakes made from hops and an everlasting yeast "starter"--and also how the yeasts are used in making bread.
The dry yeast cakes are made in part by boiling the blossoms of the hop vine. These flowers contain a fragrant yellowish oil called lupulin. The use of this oil as a preservative in beer and as a narcotic drug originated in Germany before Charlemagne. Since then its use has become widespread and the vine cultivated in other nations, including America.

Building and encouraging alternatives to the single-occupant vehicle, or, for short "alternative transportation," is imperative. Some alternative transportation advocates have taken to using the term, sustainable transportation, instead of the previous, widely-used "alternative transportation" term to avoid sidelining their interest from the mainstream. Many efficient, practical, and inexpensive sustainable transportation technologies already exist, meaning activism, policy work, and planning research is most often more crucial to developing sustainable transportation than technology development. |
