Take the yolks of three hard-boiled eggs, add salt and mustard to taste; mash it fine; make a paste by adding a dessertspoon of olive oil or melted butter (use butter always when it is difficult to get fresh oil); mix thoroughly, and then dilute by adding gradually a tea cup of vinegar, and pour over the lettuce. Garnish by slicing another egg and laying over the lettuce. This is sufficient for a moderate-sized dish of lettuce.
