"The edible bird's nests are among the most expensive animal products used by humans," said Gerbstadt "One bowl of soup is about $30-100 American dollars. One kilogram of the nests can cost $2,000 and there's another form of a red nest than can cost up to $10,000 per kilogram."
Gerbstadt said that traditionally, bird's nest soup was thought to improve the voice, to strengthen the immune system or aid digestion.
Modern science found that the bird's nests used in bird's nest soup are chock full of minerals.
"The nests do have a lot of calcium, iron, potassium and magnesium," said Gerbstadt.
Boodog is more of a cooking method than a particular dish, but its ingenuity allows for cooking outdoors in a short amount of time while simultaneously creating a stew -- inside a goat.
"It is a Mongolian cuisine dish," said Gerbstadt. "They use chunks of mutton, they put it into the abdominal cavity of a deboned goat or marmot."
The process actually starts with the beheading of the goat, the clearing of its insides and the deboning of the carcass.
Then, seasonings, chunks of other meat or the more appetizing organs are stuffed in the abdominal cavity along with stones that were preheated on a fire. The goat is sewed up again and cooked from the inside out by the hot stones, while the cook torches the skin to remove the fur from the outside.
Cooks must be careful to pay attention to the balance of temperature, or the boodog might explode.
Gerbstadt said the nutritional value will be similar to other dishes of mutton or goat. However, the organs might add a little boost -- or danger.
"The liver is kind of like the toxic waste dump of the body," said Gerbstadt. "There could be heavy metals in it; there could be a lot of cholesterol because that's the site of cholesterol synthesis."
Gerbstadt said kidneys, however, would provide quite a bit of protein and iron.
"You want to make sure they [boodogs] are cooked to 160 degrees to kill any parasites," said Gerbstadt.
