Cooks' notes:
·Buttercream can be made 1 week ahead and chilled, covered, or frozen 1 month. Bring to room temperature (this may take up to 3 hours; do not use a microwave) and beat with an electric mixer before using.
·The egg whites in this recipe are not cooked. If salmonella is a problem in your area, you can use reconstituted powdered egg whites such as Just Whites.
