As mentioned on the fun stuff topic, I bought these online and they arrived yesterday. I vaguely planned to have some for breakast, but that didn't work out so I decided to just have a small taste before comitting to a full meal. They are sold as goose liver (foie gras) sausages, although the main component is goose breast meat, with liver coming second. They come from Heilongjiang, China's northernmost province bordering Siberia, Russia.
I had 500 grams / 17.64 ounces total or four fat sausages each about 18 cm / 7 inches long, took one and sliced it on a bias. Fried them up and tasted just with some blck pepper. No salt required (see ingredient list below for a formidable list of sodiums).
Before I knew it, I had eaten a whole sausage (just to taste, you understand). They are rather good.
Ingredients as listed - my translation:
Goose breast meat, foie gras, water, starch salt, soft white sugar, spices, food additives (sodium glutamate, sodium tripolyphosphate, sodium pyrophosphate, sodium hexametaphosphate, sodium nitrite), pig casing.
All good stuff!
