Heat butter, add sliced turnips or artichokes and stir them in the butter, add flour, salt, hot milk, hot water, stirring them in slowly. When the vegetables are done rub them through a sieve, put them back in the saucepan, add a little sugar and more seasoning, if required, and heat thoroughly. A little cream or butter may be put into the tureen, and the soup stirred into it.
