take a medium-sized pot with a lid and put the asparagus peelings and trimmings in it. It is a good idea to flatten them so that less water is needed for cooking. Then pour in cold water and bring to the boil. Cook the peelings in a closed pan for 30 minutes, no longer, otherwise the soup will become bitter.
cook the asparagus pieces in a second saucepan, set them aside and pour the cooking water into the bowls, you will need about 1 litre of soup in total.
melt the butter in the saucepan and prepare a light-coloured roux. Gradually add the strained cooking water from the asparagus peelings, stirring with a whisk. Leave the soup to simmer for about 10 minutes and flavour with salt, sugar, lemon juice and nutmeg. If desired, you can refine with a dash of cream and add the pre-cooked asparagus pieces.
tips: If the asparagus itself was not bitter, this soup will not be either, it makes an excellent tasting starter soup for all kinds of asparagus dishes.
it is possible to freeze asparagus peelings at -20 °C and collect them throughout the season so that you can also cook cream of asparagus soup later in the year.
