Let’s start preparing this appetizing asparagus appetizer by cleaning and washing the asparagus; then, steam them in the special basket, it will take about 10 to 12 minutes depending on the thickness and freshness of the asparagus. When cooked, put them spaced apart on a plate to let them cool.
In the meantime, prepare the sauce by blending the anchovy fillets together with the yolks, lemon juice, sugar, mustard and a few drops of Tabasco until we obtain a homogeneous cream. We add, continuing to whisk, the oil slowly. If the sauce is too thick, dilute it with a few tablespoons of vegetable broth.
We take back the asparagus and start cutting the tips before putting them aside; instead, cut the tender part of the stems into small pieces. Put the stems in a bowl and add the sauce and parmesan flakes. We mix everything before covering with the asparagus tips. Finally, add finely chopped chives to our asparagus appetizer and serve.
