may be gradually increased. The clear spot on the egg is an infallible
test of the right quantity of oil. If too much oil is added the
dressing will curdle. A few drops of lemon-juice and long beating
will usually make it right again. If this fails, set the bowl directly
on the ice in the refrigerator, and let stand for half an hour.
If it is still curdled, begin again with the yolk of another egg
and add the curdled mayonnaise by degrees to the new dressing.

When the mayonnaise is so thick that it is difficult to stir it,
add the juice of half a lemon, if desired.
