Black Fungus (Mushroom)
Although distinct from wood ear fungus, the two are closely related and used similarly. Black fungus has an umami aroma but is extremely mild in flavor and mostly valued for its texture. Typically available in a dried form, resembling seaweed from certain angles, it transforms into a somewhat jelly-like consistency after being soaked for an hour for reconstitution.
The mild flavor lends itself as a complement to other ingredients, even desserts, which you’ll mostly find in Cantonese cuisine. Black fungus takes on the flavors of the ingredients it’s cooked with while providing extra bite in the texture of a dish, so is popular in soups and some stir fries.
Nutritionally, it’s high in fiber and has an additional bonus of containing the main electrolytes — that is, calcium, potassium, sodium, and magnesium — plus phosphorus and folate. Traditionally, it’s also been used to fight sore throats and other ailments.
