how long to whip egg whites
Egg whites right out of the refrigerator will not whip well. 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.
