Wood Ear Mushroom
Auricularia auricula-judae
Wood ear mushroom (목이/木耳) is recorded in the Donguibogam under 채부 목이조, classified as neutral with sweet flavor. The name literally means 'tree ear,' perfectly describing its shape and habitat. In Korean cuisine, wood ear is valued primarily for its unique crunchy-gelatinous texture rather than flavor — it adds a distinctive bounce to stir-fries and noodle dishes. In traditional medicine, it is particularly noted for blood-nourishing and intestine-lubricating properties. The dark color associates it with the kidney in five-element theory.
New to Wood Ear Mushroom?
Is this edible?
Yes! Wood ear mushrooms (also called cloud ear or tree ear mushrooms) have been eaten in Korean and Chinese cuisine for centuries. They are prized for their unique crunchy-slippery texture and are used in stir-fries, soups, and japchae.
What does it taste like?
Nearly flavorless on its own — the appeal is entirely textural. Wood ear has a unique crunchy-yet-silky texture, like a cross between a jelly and a chip. It absorbs the flavors of whatever it is cooked with.
Where to buy
Korean or Asian grocery stores (H Mart, 99 Ranch) sell dried wood ear mushrooms in the dried goods aisle. They are inexpensive and shelf-stable for years. Some stores carry fresh wood ear in the produce section.
How to prepare
Soak dried wood ear in warm water for 20-30 minutes — they expand dramatically (5-10x their dried size). Trim any hard, woody spots at the base. Rinse well. Cut into bite-sized pieces if they are large.
Pro tip: Start with a much smaller amount than you think you need — dried wood ear expands enormously when soaked. A small handful of dried pieces will fill a large bowl once rehydrated.
