42. DUTCH SAUCE.
Put the yolks of six eggs, a small piece of glaze, six ounces of fresh
butter, a spoonful of white sauce, some nutmeg, mignonette pepper,
and salt, into a small stewpan; stir these quickly with a wooden
spoon, over a slow fire, or else immerse the bottom of the stewpan
into a deep saucepan half full of boiling water, which must be kept
over a slow fire while the sauce is worked; as soon as the sauce
assumes a smooth compact body, take it away from the fire, work it
smartly, and then pass it through a tammy into a bain-marie for use.
If the sauce should appear to curdle or decompose, add a spoonful
of any white sauce nearest at hand, which will set it right again.
Dutch sauce may be flavoured with various sorts of vinegar, horse-
radish, or lemon-juice, according to fancy, or as the case may require.
