I made a new frosting recipe tonight and frosted some cupcakes to share with neighbors tomorrow. Can they sit out or do they need to be refrigerated?
Ingredients: butter, vanilla and almond extracts, powdered sugar, cream
Try this as a guide: How would you treat the individual components? You have to look at the most perishable ingredient and use that as your guide. BUT, if it is a very small amount of cream and a large amount of sugar, you can disregard a tiny bit of cream. If I assume that the cream amount was insignificant, then the butter is the most perishable and it can sit out a few days.
Thanks, scp1127. It is a small amount of cream. I thought it should be okay, but since it is a new recipe, I am glad to hear another's advice.
When I'm in doubt, I look up these questions on the FDA and other .gov sites. You can find dairy, egg, etc., safety information. If you sell it, looking it up and following these guidelines is a good way to head off any problems.
