66—Butter Sauce

Mix two oz. of sifted flour with two oz. of melted butter. Dilute with one quart of boiling water, salted to the extent of one-quarter oz. per quart. Stir briskly to ensure a perfect leason, and do not allow to boil. Add immediately the yolks of six eggs mixed with one-quarter pint of cream and the juice of half a lemon. Rub through a tammy, and finish the sauce with five oz. of best fresh butter.

Be careful that the sauce does not boil after it has been thickened.
