"Cut an onion into thin slices and fry in 3 tablespoonfuls of butter 10 minutes, being careful not to scorch it. Add the asparagus that has been boiled, into the stock. Cook for 5 minutes, stirring constantly.
"Add 3 tablespoonfuls of dissolved flour; cook 5 minutes longer. Turn this mixture into the boiling stock, and boil for 20 minutes. Rub through a sieve. Add milk and cream to desired taste, and add the asparagus heads. If water is used in place of stock, use all cream."
