Savoury Custard Sauce, for Boiled Chicken. (German Cook. 1889.)
Put 2 ozs. of fresh butter to melt in a saucepan, stir 2 tablespoon-fuls of flour with the butter to a paste. Next add about ½ pt. of chicken broth which you have flavoured with onions and parsley, peppercorns and a few cloves, also ½ pt. of new milk to the flour and butter. Stir all well together to prevent it from getting lumpy, till it boils. Flavour it with a little salt and cayenne.
When it is ready to serve round the boiled chicken, mix in the yolkes of 2 or 3 eggs and add a squeeze of lemon juice.
