I'll mention mushrooms once more because I don't know who buys this, or why, but it's available everywhere in multiple brands. With such a wide range of fungi available, what possesses them?
S: 香菇酱; T: 香菇醬 (xiāng gū jiàng) is industrial paste made using the most common mushroom here - 香菇 (xiāng gū) in Mandarin Chinese; hoeng1 gu1 in Cantonese; しいたけ or 椎茸 in Japanese; Lentinula erodes in Latin; and known in English as 'shiitake' from the Japanese.
These are mixed with oil, doubanjiang (broad bean sauce), sweet bean sauce, fermented black bean, chilli, sesame, salt and sugar - all standard pantry items here.
What people do with the stuff is a mystery; no one I know admits to using it. Pretty jar though.
This one costs 15.90元 / $2.30 USD for 230 grams.
Pass.
