How do you cook Wood ear?

You can dry it, rehydrate it and cook it thoroughly. Its texture is soft and gelatinous. Ground dried mushrooms absorb liquid in soups and stews. Cultivated Auricularia heimuer appears in hot and sour soup and in salads after cooking.[7][10]

Where and when does Wood ear grow?

It grows on broadleaf wood, including elder. It decomposes wood.[5][6]

A Mexican fruiting season awaits confirmed records using the current species boundaries.[4]

The species in its strict sense occurs in Europe. A Mexican revision left its presence in Mexico unconfirmed and reassigned earlier specimens to Auricularia americana and Auricularia angiospermarum.[4][5]

About the name

DNA studies separated several species formerly grouped under Auricularia auricula-judae. In its strict sense, the name applies to the European species; Auricularia heimuer is the cultivated Asian wood ear frequently labeled with that name.[5][7]

Fun facts

  • The dried mushroom expands when you rehydrate it.[7]
  • The name Judas's ear is linked to a legend about Judas and an elder tree.[8]
