Irish moss + Prairie turnip

Chondrus crispus ? commonly called Irish moss or carrageen moss (Irish carraigín, "little rock") ? is a species of red algae which grows abundantly along the rocky parts of the Atlantic coast of Europe and North America. In its fresh condition this protist is soft and cartilaginous, varying in color from a greenish-yellow, through red, to a dark purple or purplish-brown. The principal constituent is a mucilaginous body, made of the polysaccharide carrageenan which comprises about 55% by weight. The organism also consists of nearly 10% protein and about 15% mineral matter, and is rich in iodine and sulfur. When softened in water it has a sea-like odour and because of the abundant cell wall polysaccharides it will form a jelly when boiled, containing from 20 to 100 times its weight of water.

Psoralea esculenta (prairie turnip) is an herbaceous perennial plant native to prairies and dry woodlands of central North America, which bears a starchy tuberous root edible as a root vegetable. The plant is also known as Pediomelum esculenta. English names for the plant include tipsin, teepsenee, breadroot, breadroot scurf pea, and pomme blanche. The prairie turnip was a staple food of the Plains Indians. A closely related species, Psoralea hypogaea, the little breadroot, is also edible, although the plant and root are smaller. Another species, Psoralea argophylla, was probably harvested for food only in times of famine.
