Ingredients

Optional Fennel oil:

Instructions

  1. In a large heavy bottom pot, saute onion and fennel in 2 T oil over medium high heat, for 2 minutes, stirring constantly. Turn heat to medium and continue cooking until softened, about 5-6 minutes. Add garlic and saute for a couple more minutes, until garlic becomes fragrant. Add water or stock and sliced potatoes, and bring to a boil. Cover, simmer on low 15-20 minutes until potatoes cooked through and are fork tender.
  2. Add asparagus, turn heat up and return to a boil, and cook for 2-3  minutes. Don’t over cook or you will loose the lovely color. Remove from heat and let cool a bit.
  3. In batches (see warning above) blend soup until creamy and very very smooth, adding in herbs. The herbs will give it this glorious color. Blend really well, so there are no specs of herbs but rather, let them tint the soup and make it very green.
  4. Return to the stove and heat gently. Whisk in ½ C Sour Cream. Do not let this soup boil, it will turn the color.
  5. As it heating …add the salt and pepper. The salt will actually bring this soup to life, so do not forget to add it. It’s like magic.
  6. TIP : If you are using any other substitute for sour cream ( cashew cream, or heavy cream)  remember that sour cream has a good bit of tang, so you may need to add a one or two drops of lemon juice or white vinegar to balance the flavors.  I have found that sour cream, has just the right balance of fat and acidity.
  7. Divide among bowls, garnish with a swirl of  sour cream if you like, fennel oil, blanched asparagus tips, or fresh tarragon.

Notes

To make Fennel Oil :

  1. Place fennel fronds and parsley in a strainer, and dip in large pot of salted boiling water for 45 seconds to blanch. Remove and immediately cool in an ice water bath, to shock ( keeping it green)
  2. Drain, and squeeze dry with kitchen towels or paper towels to remove as much water as possible. Place in a blender, with just enough oil to cover, about ¾ Cup (or less is fine too), blend, adding a little more oil if necessary, to keep the blade turning.  (Keep in mind, the less oil you use, the more flavorful this will be.) Blend for a full minute, until fairly smooth. Let this sit in the fridge, as long as possible, preferably overnight or even for a couple of days. Strain with a fine-mesh strainer or cheesecloth. Pour into a squeeze bottle. This keeps for a week or two in the fridge or can be frozen.
