Wash
the asparagus really well and trim off the tips to about 4 -5 cm
long (or 2-2 1/2 inches). Removed about 2 cm (or 1 inch) from the
bottom of the stalk. Peel the bottoms of each stalk up to where
the green begins. Cut the stalks into pieces about 1 cm (1/2 inch)
long.
In
a pot bring 1-1/2 liters of water with 2 tsk salt to a boil add
the asparagus stalks and boil gently for 5 minutes. Remove the asparagus
and keep the cooking water back on the heat and toss in the asparagus
tips and gently boil for 6 to 8 minutes or until they are just cooked.
Remove the tips and plunge them into ice water to bring back their
color, when cold, drain and set aside. Keep the cooking water.
In
another pot, on a medium heat place all the sliced onions and the
first 2 msk. (or 2 tbls.) of butter and cook the onions for 10 minutes
until they are translucent and soft. Avoid coloring them, you want
them to be still white.
Now
add the cooked stalks to the cooked onions and cook for a few 5
minutes uncovered.
Add
the flour and cook for another minute or two. Then add the hot cooking
liquid slowly, stirring with a wooden spoon, then the milk. (take
care that there is no sand in the bottom of the cooking water).
Simmer
this gently for about 20 minutes or until the asparagus are very
tender and soft.
If
the soup seems too thick you can thin it with a bit of warm water.
Remove
the soup from the stove and let cool for a little while. Place the
soup into the container of your food processor or blender and blend
until smooth. Then pass the soup through a sieve to remove any course
fibrous threads in the soup. If you do not have a food processor
or if you have a food mill you can pass the soup through a food
mill to accomplish the same thing all in one step.
Heat
the soup gently, add the nugmeg if you are using it, mix the cream
and eggs yolks together well, then whisk this into the warm soup
a bit at a time to thicken and enrich the soup. With a wooden spoon
stir the soup while it is heating, scraping the bottom and sides
of the pot to avoid the yolks making the soup stick. Remove from
the heat just before the soup comes to the boil to avoid the eggs
from scrambling.
Taste
and check for salt and white pepper.
The
soup can be prepared up until this point.
To
serve it warm: Put the soup in a pot over a medium heat
and warm until it is just hot. Whisk in the butter pour into soup
bowls garnish with 4 or 5 asparagus tips and serve.
To
serve it cold: Don't add the final 2 msk (or 2 tbls.) of
butter. After it is chilled correct for salt as cold soup usually
needs a bit more seasoning. You can also add an extra msk (or tables.)
of cold whipping cream for each bowl of soup you are serving. |
