Separating egg yolks the night before beating meringue - A Person Separating Egg White

When separating egg whites from yolks could a person do it the night before so the morning of making pies turns out faster?



Best Answer

Yes, that's fine - if you take a few precautions.

Once you have opened your eggs, you are exposing the contents to the air. So need to protect the eggs from drying out: A matching small jar or plastic container is a good choice for the yolks. For whites, you can even put them in your mixing bowl and cover tightly, which saves on cleanup.

You need not worry that your whites won't whip properly, many macaron bakers even recommend "aging" the whites, i.e. storing them for a day or so in the fridge. (But there is also a wild debate on whether this is really necessary.)

For food safety reasons, storing your separated eggs in the fridge is a must. And please remember that while you can certainly separate the eggs the night before, longer storage will affect the quality negatively, less so for the whites, but please use the yolks as soon as possible.

Can you leave egg yolks out overnight?

"After eggs are refrigerated, they need to stay that way," the USDA website explains. "A cold egg left out at room temperature can sweat, facilitating the movement of bacteria into the egg and increasing the growth of bacteria. Refrigerated eggs should not be left out more than two hours."

How long should egg whites sit out before making meringue?

The ideal temperature to whip a common meringue is room temperature, about 70 degrees F. (21 degrees C.). Usually 30 minutes is adequate to obtain room temperature. A beaten egg white can foam to 6 to 8 times its original volume if the egg whites have been at room temperature for 30 minutes before beating.

Will egg yolk prevent stiff peaks?

In any case, with that single drop of yolk, the whites still managed to form both soft and stiff peaks, but it took longer: about five minutes for soft peaks, and six minutes 45 seconds for stiff peaks. Clean whites at left and whites with one drop of yolk at right, both beaten until very stiff.
