Peel the asparagus and cut into bite-sized pieces.
Fry briefly in butter and oil in a pan, season with salt, add a little (approx. 50-100 ml) water and let cook. When the asparagus is done, stir in the starch dissolved in a glass of water to create a thick sauce. Bring to the boil briefly. Season to taste with salt and pepper and stir in freshly chopped herbs to taste.
