In the proportions of two egg yolks to half a pint of Lucca oil, and a small wine-glassful of tarragon vinegar. Work the yolks smooth in a basin, with a seasoning of pepper (cayenne for choice), salt, and--according to the writer's views--sifted sugar. Then a few drops of oil, and fewer of vinegar; stirring the mixture all the time, from right to left, with a wooden, or ivory, spoon. In good truth 'tis a "fatiguing" task; and as in very hot weather the sauce is liable to decompose, or "curdle," before the finishing touches are put to it, it may be made over ice. "Stir, sisters, stir, Stir with care!" is the motto for the _Mayonnaise_-mixer. And in many cases her only reward consists in the knowledge that through her art and patience she has helped to make the sojourn of others in this vale of tears less tearful and monotonous. "Onion atoms" should "lurk within the bowl," on nearly every occasion, and as for a potato salad--don't be afraid, I'm not going to quote any more Sydney Smith, so don't get loading your guns--well, here is the proper way to make it. _Potato Salad._ Cut nine or ten average-sized kidney potatoes (cooked) into slices, half an inch thick, put them in a salad bowl, and pour over them, after mixing, two tablespoonfuls of vinegar, one tablespoonful of tarragon vinegar, six tablespoonfuls of oil, one of minced parsley, a dessert-spoonful of onions chopped very fine, with cayenne and salt to taste. Shredded anchovies may be added, although it is preferable without; and this salad should be made a couple of hours or so before partaken of. The German recipe for a potato salad is too nasty to quote; and their HERRING SALAD, although said to be a valuable restorative of nerve power, by no means presents an attractive appearance, when served at table. Far more to the mind and palate of the average epicure is a _Tomato Salad_. This is the author's recipe: Four large tomatoes and one Spanish onion, cut into thin slices. Mix a spot of mustard, a little white pepper and salt, with vinegar, in a table-spoon, pour it over the love apples, etc., and then add two tablespoonfuls of oil. Mix well, and then sprinkle over the mixture a few drops of Lea and Perrins's Worcester Sauce. For the fair sex, the last part of the programme may be omitted, but on no account leave out the breath of sunny Spain. And mark this well. The man, or woman, who mixes tomatoes with lettuces, or endives, in the bowl, is hereby sentenced to translate the whole of this book into Court English. _Celery Salad._
