30—Hollandaise Sauce

Quantities Required for One Quart.—One and one-half lbs. of butter, the yolks of six eggs, one pinch of mignonette pepper and one-quarter oz. of salt, three tablespoonfuls of good vinegar.

Preparation.—Put the salt, the mignonette, the vinegar, and as much water in a small saucepan, and reduce by three-quarters on the fire. Move the saucepan to a corner of the fire or into a bain-marie, and add a spoonful of fresh water and the yolks. Work the whole with a whisk until the yolks thicken and have the consistence of cream. Then remove the saucepan to a tepid place and gradually pour the butter on the yolks while briskly stirring the sauce. When the butter is absorbed, the sauce ought to be thick and firm. It is brought to the correct consistence with a little water, which also lightens it slightly, but the addition of water is optional. The sauce is completed by a drop of lemon juice, and it is rubbed through a tammy.

Remarks.—The consistence of sauces whose processes are identical with those of the Hollandaise may be varied at will; for instance, the number of yolks may be increased if a very thick sauce is desired, and it may be lessened in the reverse case. Also similar results may be obtained by cooking the eggs either more or less. As a rule, if a thick sauce be required, the yolks ought to be well cooked and the sauce kept almost cold in the making. Experience alone—the fruit of long practice—can teach the various devices which enable the skilled worker to obtain different results from the same kind and quality of material.
