About Sauces
So much depends on sauces that only the best ingredients should be used in making them. Rancid or impure oil or bad butter will ruin sauces and salads. Both butter and oil should always be tasted before buying, as good cookery is impossible unless they are perfectly fresh and good in every way; butter must be added to sauces in small bits, or it will form a greasy line. To skim sauces, take the sauce-pan off the fire and put in a teaspoonful of cold water, which will make the grease rise. Remember that wine increases the taste of salt, so when wine is used in a sauce put in very little salt until after the wine has been added.
