Rinse the white asparagus under cold water. Using a vegetable peeler, carefully peel each spear from just below the tip to the base. Cut off and discard the woody ends (about 1 inch from the bottom).

Slice the peeled asparagus into bite-sized pieces, about 1-inch long. Try to keep them relatively uniform for even cooking.

Place the asparagus pieces in a large pot with the water, salt, and sugar. Bring to a gentle boil and cook for about 15 minutes until tender. Strain through a colander, making sure to collect and reserve the cooking liquid - this flavorful broth is the base of your soup!

In a clean pot, melt the butter over medium heat. Stir in the flour to create a paste (roux). Cook for 1-2 minutes, then gradually whisk in the reserved asparagus broth until smooth. Let it simmer gently for a few minutes until it begins to thicken.
