Some recipes say let the ingredients come to room temperature while others don't specify. Does it just not matter on some recipes? Thanks!

I make cheesecakes with room temp. stuff. I don't use room temp stuff unless a recipe calls for it. After you bake for a while even if the recipe doesn't specify you will just intuitivley know what works better. If you forget to leave your ingredients out just put your eggs in warm water for a few mins. and your butter in the micro for tiny, tiny, short periods of time. There shouldn't be any part of it turning to liquid. Hope this helps.

sometimes room temp. ing. just mesh and mix up better than cold.

room temp stuff mix better than cold. its easier to seperate cold eggs than room temp eggs. thats the only time i dont let the eggs get to room temp. otherwise all my ingredients are room temp.
