I came across mock shark fin while dining at Sushi Express two years ago.
This was the Appetizer served at Sushi Express but this item is now discontinued.
Half packet frozen mock shark fin (vegetarian)
Six pieces dried Shiitake mushroom (soaked in warm water and sliced thinly)
Ten pieces dried black fungus (soaked and trimmed)
Salt and pepper to taste
Thawed the mock shark fin.
Rinsed with tap water a few rounds. The final round pour some hot water for final rinsing and set aside.
Leave it to cool and marinate with sesame oil.
Heat up wok, add a little cooking oil and minced garlic. Sautéed.
Add the thinly sliced Shiitake mushrooms and black fungus and mixed well and cook for a few minutes.
Add the mock Shark Fins, Hoisin sauce, fish sauce, salt and pepper and blend well.
Taste and adjust the seasoning.
Do not overcook the mock Shark Fins.
Transfer to a plate and serve.
