In France, there are special asparagus plates that have a “sauce well” at the side, in which one can make one’s own sauce from oil, vinegar, blood orange, or lemon juice, salt and pepper, mustard and so on. I have never seen them in the United States, but this recipe gives you the idea. Put the individual ingredients in pots or jugs on the table and then mash up your chosen ingredients on your plate to make a sauce for dipping the asparagus (hot or cold). If you don’t have asparagus plates, use large, shallow soup plates.
