"Aspergesoep is afvalsoep" I read somewhere on the internet, and I'd have to agree: asparagus soup is made with all the waste from an asparagus dinner. But what a soup! The sweet earthy flavor of the asparagus and the soft, silky mouthfeel is comforting but not heavy.
Cut up the remaining ham of your dinner in small dice, and chop some parsley. Taste the soup and adjust it with salt if needed, then stir in 1/4 cup of cream or whole milk. Divide the asparagus points over four bowls, ladle the hot soup on top, sprinkle with parsley and enjoy!
After you prepare asparagus for dinner, boil the skins and the end pieces in the remaining asparagus water, cover and simmer for a good thirty minutes, then put the liquid through a sieve. You should have about four to five cups of vegetable broth. Add half a bouillon cube of chicken stock to the broth.
Save four or five asparagus from dinner, and cut them into three or four pieces. Keep the heads and add the rest to the soup. Purée into a homogenous whole. Now melt two tablespoons of butter in a pan, add two heaping tablespoons of flour, stir until you have a paste and add in a ladle full of hot soup. Keep stirring and add one or two more ladles of soup...then pour everything into the big pot, stir until it all comes together and simmer it for another five minutes.
