Yeast Cakes from Hops
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-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.

Planted cattails at Millcreek greywater
Greywater, sometimes also spelled as graywater, grey water or gray water, is all of the effluent water from a household, such as water discharged from lavatories (bathroom sinks), bathtubs, showers, clothes washers, and laundry trays. Greywater is not wastewater from a sink used for food preparation, or water closet (toilet) wastewater.

The water leaving our homes carries nutrients and value. It may also contain pathogens, and/or harsh chemicals and care should be taken with it. However, it is not a great risk compared to blackwater (sewage).

Redirecting the water we use for tasks such as showering allows us to reclaim some of that value to grow plants and recharge the water table. It may be necessary to choose our soaps and detergents more carefully, if we use the greywater for watering and fertilizing plants.
