Have some friends that want me to cater a small office party of 50 people, they love my wifes potato salad and are requesting it on the menu, bbq btw. Not everyone will eat at the same time due to different lunch breaks. I have heard that potato salad must stay cold or it will turn bad, is this true and if so what makes it go bad? We usually use eggs in it and mayo so wondering of its one o these two that is the problem.
thanks in adbvance
