I know that whole eggs and egg yolks whip up greater and have more air when beaten with heat, but does the same hold true for egg whites? Would it be beneficial to whip them over a double boiler or not? Thanks!
actually for egg yolks it does the heat help on that, for egg whites they should be at room temperature not cold because at room temperature reaches maximum volume faster than cold egg whites, and the utensils used like the electric or hand mixer and bowl must not have any trace of grease because fat inhibits the raise process. with taking care of this you will get a good volume of the egg whites, also take into account that if the eggs whites contains sugar it will stabilize the egg foam,with this the meringe (yes now it has become a meringue is you gonna do that) wont go down after a long time, also depending in the manner that you made it either swiss,french, or italian way,if your recipe calls for that then do it, if not, dont.
You can add cream of tartar, which will break down the protiens in the egg whites to get the whipped stage faster and stronger.
cool, but the question is about beating eggs over a double boiler. This doesn't answer the question.– LucianoAug 1, 2019 at 11:28
