Peel the white asparagus and remove the tough and woody ends.

Bring the water to a boil in a large pan or a wide saucepan. Season it with salt, sugar and lemon juice. Add the asparagus, bring it to a boil and then let it simmer over low heat for about 12-15 minutes. If you like your asparagus extra soft, you should extend the cooking time accordingly.

For the hollandaise sauce melt vegan butter in a pot on low to medium heat. Stir in the flour. Add vegetable stock gradually while stirring.

Add the remaining ingredients slowly while stirring and bring to a boil carefully. Serve directly with the asparagus.
