For the glazed asparagus, wash the asparagus and peel or cut off the back third. Cut the asparagus spears into bite-sized pieces.
Heat the butter in a sufficiently large pan, add the sugar and let it brown slightly. Add the asparagus pieces, fry briefly and add the water.
Add a little salt, cover the pan and let the asparagus simmer for 4 minutes. Then remove the lid and cook until all the water has evaporated and all the asparagus pieces are glossily coated, shaking the pan repeatedly.
