Can or should I make potato salad a day ahead? Also, if you were making cake and cupcakes ahead would you put them in the fridge, freezer or leave them out?
I think potato salad the day before is OK, as long as it's kept in the fridge lol. Cake or cupcakes I would keep out. But don't ice (icing??) them. I would make your cake or cupcakes the day before, leave them out. Make the icing and store it separately in the fridge. Then ice them the day of or just before the party.
I'd actually make and frost the cupcakes, put them in a disposable aluminum pan with a plastic lid, wrap it really well in plastic wrap, and then freeze them. Last year I made cupcakes for DS's birthday (mid-December) and doubled up the recipe, frosting/decorating half of them for the birthday and half for Christmas. I think they came out just fine, and they seemed pretty popular at the Christmas party.
