is the site for collaborative solutions in sustainability
reduction and international development
through the use of sound principles
and appropriate technology
and the sharing of wisdom and project
information. It is a wiki
, a type of website which allows anyone to add, remove, or edit content. Registration is encouraged but not required for contributors.
Appropedia has been described as an "appropriate technology wiki," but it is much broader than that - it is a green wiki, and a wiki for all matters of international development and aid. But most importantly, Appropedia is an open site for stakeholders to come together to find, create and improve scalable and adaptable solutions. For more about our motivation, see Appropedia:Mission.

Yeasts for Baking
. Generally when one mentions yeast, aromatic loaves of fresh homemade light bread come to mind. And so they should. Aside from acting as a leavening agent in bakery products, yeast is also the ingredient responsible for the tantalizing aroma that arises during baking.
Though probably today the most commonly known and used are store-boughten 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 wide spread and the vine cultivated in other nations, including America.
The hop vine is related to the hemp and mulberry plants in the nettle family. The plant itself is twenty-five to thirty feet in length with rough lobed leaves and flowers that grow on catkin clusters. It is quite possible that many people in the Ozarks have never seen a hop vine, because although some Ozarkians have had limited success cultivating it, it grows best in sandy coastal regions.
