Will wonders at the Korean market never cease?! Sahm-gyae-tahng (that's my spelling, but others may Romanize it differently) is a Korean chicken soup made by boiling a whole young chicken that is stuffed with sweet rice, ginseng, and Korean dates (jujubes). It supposed to simmer for a long time on the stove top to draw all the nutrients out of the chicken's meat and bones, so it's supposedly served as a "healing" soup.
At the market, I came across sahm-gyae-tahng all ready to go in a bag - rice, dried ginseng, Korean dates, and even the seasonings. All you have to do is add a chicken and follow the directions on the package. Kind of like those Hormel add-your-own meat mixes.
