Many recipes call for ingredients that are normally stored cold to be at room temperature at the time of use. One example is a cake recipe, which often calls for all ingredients (milk, eggs, etc) to be at room temperature.
What is the safe method of bringing these ingredients to room temperature? Do you just leave them out for a few hours?
Alternatively, what is a quick way to accomplish this? Heat them up? Place them in room temperature or warm water baths?
