HOW TO MAKE CREAM SOUPS Cream soups are all made by blending two tablespoons of butter with two tablespoons of flour and then adding slowly one cup of cold milk or half cream and milk. One cup for a thin soup or purée, to one quart of liquid. More according to the thickness of soup desired. Any cooked vegetable or fish may be added to the cream sauce. Less milk is used when the water in which the vegetables are cooked is added. Purées are made from vegetables or fish, forced through a strainer and retained in soup, milk and seasonings. Generally thicker than cream soup. Use a double boiler in making cream sauces and the cream sauce foundation for soups. To warm over a thick soup it is best to put it in a double boiler. It must not be covered. If one does not have a double boiler set soup boiler in a pan of hot water over fire.
