When to bring eggs whites to room temperature? I’m looking over a recipe for angel food cake that calls for twelve egg whites at room temperature and it got me wondering about what’s the best way to do it. Is it best to bring the dozen of eggs to room temperature on the counter, crack them, separate them, and then put the yolks back in the fridge for another recipe? Or is it best to crack and separate the eggs while cold, throw the yolks back in the fridge, and let the egg whites warm up in a sealed container on the counter?
Just curious and figured I’d ask in case there’s a good reason for either of these or something else.
It doesn't make much difference to the end product whether you separate them cold or warm as long as the egg whites are room temperature when you whip them. Cold whites won't get as fluffy and therefore you'll get a denser cake. Oxygen will cause chemical changes in the white as it warms up to temperature, but that's minor.
It is easier to separate eggs that are at room temperature as the whites run much more easily, so if my eggs are refrigerated I would bring them up to room temperature first, then separate and put the yolks in the fridge. You can do this quickly by putting the eggs in a bowl of tepid water.
