White Sauce. No. 2.
Put 1 oz. of butter in a stewpan to melt; add 2 tablespoonfuls of flour and mix well; then add 1 pt. of first stock, ½ a carrot sliced, a bunch of sweet herbs, and button mushrooms or mushroom peelings to flavour the sauce, ½ oz. of lean ham cut into little bits. Boil it up, then let it simmer for 1 hour, skim all the fat off, put through a tammy, and season it; add a gill of cream, and give a warm up, but not a boil.
