Two eggs, three table-spoonfuls of vinegar, one of cream, one teaspoonful of sugar, one-fourth of a teaspoonful of salt, one-fourth of a teaspoonful of mustard. Beat two eggs well. Add the sugar, salt and mustard, then the vinegar, and the cream. Place the bowl in a basin of boiling water, and stir until about the thickness of rich cream. If the bowl is thick and the water boils all the time, it will take about five minutes. Cool, and use as needed.
Lobster "coral" is pounded to a powder, rubbed through a sieve, and mixed with mayonnaise dressing. This gives a dressing of a bright color. Or, the juice from boiled beets can be used instead of "coral."
Mix enough spinach green with mayonnaise sauce to give it a bright green color. A little finely-chopped parsley can be added.
Melt, but heat only slightly, one cupful of aspic jelly; or, one cupful of consomme will answer, if it is well jellied. Put in a bowl and place in a basin of ice water. Have ready the juice of half a lemon, one cupful of salad oil, one-fourth of a cupful of vinegar, one table-spoonful of sugar, one scant table-spoonful of mustard, one teaspoonful of salt and one-tenth of a teaspoonful of cayenne. Mix the dry ingredients with the vinegar. Beat the jelly with a whisk, and as soon as it begins to thicken, add the oil and vinegar, a little at a time. Add the lemon juice the last thing. You must beat all the time after the bowl is placed in the ice water. This gives a whiter dressing than that made with the yolks of eggs
Three eggs, one table-spoonful each of sugar, oil and salt, a scant table-spoonful of mustard, a cupful of milk and one of vinegar. Stir oil, salt, mustard and sugar in a bowl until perfectly smooth. Add the eggs, and beat well; then add the vinegar, and finally the milk. Place the bowl in a basin of boiling water, and stir the dressing until it thickens like soft custard. The time of cooking depends upon the thickness of the bowl. If a common white bowl is used, and it is placed in water that is boiling at the time and is kept constantly boiling, from eight to ten minutes will suffice; but if the bowl is very thick, from twelve to fifteen minutes will be needed. The dressing will keep two weeks if bottled tightly and put in a cool place.
One cupful of sour cream, one teaspoonful of salt, a speck of cayenne, one table-spoonful of lemon juice, three of vinegar, one teaspoonful of sugar. Mix all together thoroughly. This is best for vegetables.
Pound in a mortar, until perfectly smooth, the yolks of four hard-boiled eggs and three sardines, which have been freed of bones, if there were any. Add the mixture to any of the thick dressings, like the mayonnaise or the boiled. This dressing is for fish.
