In order to guarantee a creamy soup, first place the cashews, lemon juice and just 1/2 cup of the stock in the blender or food processor. Blend to create a creamy liquid. Then add zucchini, basil, garlic, miso, remaining vegetable stock and 1-2 teaspoons salt in the blender or food processor.
This soup is delicious! Great way of using summer, zucchini, and basil. Adding mint takes it to the next level. Note to Cooking editors: it would be most helpful if you indicated the yield in cups rather than four servings. Who is to say how much is in a serving? If I knew this yielded 6 cups, I would’ve used a food processor instead of a blender. Using a blender, I had to do the recipe in multiple batches. From start to finish it took me 45 minutes to prepare this soup. Worth it.
David, I’d soak almonds for a few hours or overnight, remove the skins, and use the hydrated nuts in place of cashews. The soaking really softens and plumps the almonds.
Wonderful soup to use the abundant zucchini we have in the summer. I used raw cashews as the roasted ones in the supermarket were all excessively salted. I couldn't find miso, so I used a tablespoon of low sodium soy sauce and low sodium chicken broth as the vegetable broth had very high sodium content. I also added about 1/4 c of extra virgin olive oil in the final blend. I think that helped create a silkier texture.
Had a vitamix, made this as shown. Used a couple slices of toasted sourdough to wipe the bowl clean. Delicious. And my wife described it perfectly: a savory smoothie :D
Let me be clearer about my previous comment about the discrepancy between the appearance of my soup and that above. The one in the picture is creamy and uniformly green, whereas my is more rustic looking - i.e., much less uniform in texture and color.
