Cut the stem end of the king oyster mushrooms, and cut them lengthwise into bite-sized pieces.
Heat the butter or margarine in a frying pan, then add the king oyster mushrooms. Sprinkle in a liberal amount of garlic powder.
Add the ponzu, then immediately turn off the heat and cook with the residual heat. Garnish with green onions and it's ready to serve.
I also tried adding shiitake mushrooms It turned out delicious. Try adding your choice of mushrooms.
Story Behind this Recipe
My butter-loving husband requested a mushroom and garlic sauté, so I came up with this dish using margarine for richness, and ponzu to give it a light and tangy touch; it was a hit Now it's a family staple.
Adjust the amount of ponzu depending on the size of the king oyster mushrooms. Since my husband dislikes strong acidic flavors, I used Mitsukan Mild Ponzu.
