Strip off the outer leaves, wash the lettuce, split it in half, and lay it in cold water till dinner time. Then drain it and put it into a salad dish. Have ready two eggs boiled hard, (which they will be in ten minutes,) and laid in a basin of cold water for five minutes to prevent the whites from turning blue. Cut them in half and lay them on the lettuce.
Put the yolks of the eggs on a large plate, and with a wooden spoon mash them smooth, mixing with them a table-spoonful of water, and two table-spoonfuls of sweet oil. Then add, by degrees, a salt-spoonful of salt, a tea-spoonful of mustard, and a tea-spoonful of powdered loaf-sugar. When these are all smoothly united, add very gradually three table-spoonfuls of vinegar. The lettuce having been cut up fine on another plate, put it to the dressing, and mix it well.
If you have the dressing for salad made before dinner, put it into the bottom of the salad dish; then (having cut it up) lay the salad upon it, and let it rest till it is to be eaten, as stirring it will injure it.
You may decorate the top of the salad with slices of red beet, and with the hard white of the eggs cut into rings.
