Step 1

Combine the porcinis and rosemary in a small bowl. Bring 1 cup of water to a boil, and pour into the bowl. Steep for 20 minutes.

Step 2

Preheat a large soup pot over medium heat. Add the onion and 1/4 cup broth. Stirring occasionally, cook 3 to 5 minutes or until translucent. Add the sliced mushrooms, and continue to cook until softened and lightly caramelized, about 15 to 20 minutes.

Step 3

In the meantime, combine the mushroom-rosemary "tea" with the cashews and 2 whole cloves of garlic in a blender. Blend until smooth, adding a bit of the broth to keep it moving, if needed. Set aside.

Step 4

To the soup pot add black pepper, 2 cloves of minced garlic, and tamari, and cook for another 2 to 3 minutes or until all moisture has evaporated.

Step 5

Add the remaining broth to the soup pot and bring to a simmer. Whisk in the blended mixture.

Step 6

Dissolve the arrowroot into the remaining cup of water. Add this to the soup pot, and continue to whisk/stir. Cook until thickened, about 3 minutes.
