- 1 shallot
- 2 teaspoons agar agar
- 1/2 liter mushroom stock or vegetable stock
- 10 chestnut mushrooms
- 15 g dried shitakes (if you haven´t used mushroom stock)
- olive oil, pepper, salt
If you are using the dried shitakes, start soaking them for 15 minutes.
In the meantime, fry the finely chopped shallot in a dash of olive oil
Drain the shitakes and cut them into pieces.
Add the sliced mushrooms and fry until nicely browned.
Bring the vegetable stock to the boil in another pan.
Add the agar agar and let it boil for a few more minutes. You will notice that the broth is thickening. If you don't see it after a few minutes, add another teaspoon of agar agar. Add the shitakes.
Now let the broth with the shiitake mushrooms cool down. A jelly-like substance is created that you will not immediately recognize as soup.
After half an hour you put the jelly in the blender or a bowl and blend it completely, including the shitakes.
Warm up the soup, add the shallots and mushrooms. If the soup is still too thick, add some water.
