Yolk of 1 egg.
1/2 cup of olive-oil.
1 tablespoonful of lemon juice or vinegar.
1/2 teaspoonful of salt.
Pinch of red pepper.
Put the yolk of the egg into a very cold bowl; it is better to put
the bowl, the egg, the oil, and the beater all on the ice a half-hour
before you need them, for then the mayonnaise comes quicker.
With a Dover egg-beater beat till the yolk is very light indeed;
then have some one else begin to put in the oil, one drop at a time,
till the mayonnaise becomes so thick it is difficult to turn the
beater; then put in a drop or two of lemon or vinegar, and this
will thin it so you can use the oil again; keep on doing this till
you have nearly a cup of the dressing; if you need more oil than
the rule calls for, use it, and toward the last add it two or three
drops at a time. When you have enough, and it is stiff enough,
put in the pepper and salt and it is done. Never use mustard
except with lobster, as this will spoil the taste. Some salads,
especially fruit and vegetable, need very thick mayonnaise, and
then it is better to make it with lemon juice, while a fish salad,
or one to use with meats, may be thinner, and then the vinegar
will do; the lemon juice makes it thick. Always taste it before
using it, to see if it is just right, and, if not, put in more salt,
or whatever it needs. You will soon learn. Most people think
mayonnaise is very difficult to make, but, really, it is as easy as
baking potatoes, after you have once learned how. Every salad
given before is just as nice with mayonnaise as with French dressing,
and you can try each one both ways; then there are these, which
are better with mayonnaise.
