#18259: Sandi, mayonnaise won't emulsify if the eggs are cold, or if there is a thunderstorm. The French say

a failed mayonnaise could also mean that you're going to have a baby. Leave it to the French to come up with a pregnancy test that is also a sauce!
Julia gives a maximum of 1/2 cup oil per egg yolk. I think this recipe needs one more yolk. Also, I've never seen a recipe without Dijon mustard, which is also an emulsifier.
Julia's method for fixing a failed mayonnaise: Warm a bowl with hot water and dry. Put a spoonful of Dijon in the bowl. (room temp.) Stir up the mixture and whisk it into the bowl by dribbles. If you go slowly, this should work.
