How to Make It
Melt butter in a heavy saucepan over low heat; add flour, stirring until smooth. Cook 1 minute, stirring constantly. Combine milk and egg yolk, stirring well; gradually add to flour mixture. Cook over medium heat, stirring constantly, until thickened and bubbly. Stir in salt, pepper, onion juice, and asparagus pieces; chill mixture thoroughly.
Shape into patties, using about 1/4 cup mixture for each. Roll patties in breadcrumbs, and place on an ungreased baking sheet. Bake at 350° for 20 minutes or until tops are golden brown. Turn and bake an additional 5 minutes.
