Help! Frosting with heavy cream and sour cream: Does it need to be refrigerated?
Need some advice! I made these whoopie pies for a work function today: http://carenblair.blogspot.com/2012/0...
I refrigerated them overnight, but this morning I took them out and have left them out of the fridge at air conditioned room temperature for about four hours, thinking that it was frosting, so no big deal.
THEN I remembered that there is sour cream and heavy cream in this frosting. Sound I not be serving these? Really don't want to make everyone sick!
