In a baking por or in a large skillet place the asparagus with salt, butter, (garlic optional) and water to barely cover.
Broil or boil for 3 to 4 minutes.
Remove them from the pot and place them over ice water if using them later on. If using them at the moment, set them aside.
Place the pot back on the heat to boil off all but 2 tablespoons of water and add the asparagus back to the pot to mix them with the reduced liquid.
Blend all ingredients (herbs, garlic, red wine vinegar, djon mustard, salt, pepper, sugar, olive oil). Note: If you want sweeter you can add honey.
