Can someone tell me what needs to be refrigerated and what doesn't? We use eggs in nearly every cake, but most don't have to be refrigerated. Why is that? Do we have to refrigerate anything with dairy in it? What about butter (technically dairy, I know)?
Thanks for the help!
cooked items, like eggs in cakes, do not generally require refrigeration. Refrigeration can be useful to prevent mold if you store cake a few days.
most fresh dairy is considered perishable, including butter. Also, butter will soften or melt in icing, refrigeration stops that.
When in doubt, refrigerate it. Carefully boxed or packaged, it will be fine in the fridge.
