Cut the asparagus in pieces of the size of a pea and cook until tender. In cooking, reserve the tips until the other pieces are partially cooked, or, being more tender, they will become broken while the others are still uncooked. Make a sauce of the butter, flour, salt, paprica, and water in which the asparagus was cooked, or use half a cup of cream in the place of part of the asparagus liquor. When the sauce boils, add the asparagus and mix lightly with the sauce; break the eggs, one after another, into a cup and slide them carefully on to the top of the asparagus. Season with a sprinkling of salt and pepper, and, if desired, a grating of nutmeg. Set the blazer into the bath and put on the cover. When the eggs are nicely poached, remove the eggs, with the asparagus below, on to rounds of toasted and buttered bread.
