This is our family's favorite icing! It's fluffy, light, smooth & sweet.
On high with an electric mixer, mix 2 egg whites and 1/4 t cream of tartar until whites from stiff peaks. Meanwhile in a saucepan, bring to boil then boil for 1 minute: 1/3 C water & 1 C sugar. After egg whites have come to stiff peaks, start mixing again & in a slow steady stream, mix in hot syrup. When fully whipped/mixed, add 1/2-1 T vanilla. When your cake or cupcakes are cooled completely, spread on your Fluffy Boiled Icing.
Optional: Add food coloring to egg whites just before adding syrup or add it to the syrup after boiling.
I'm such an amateur icer, excuse my piping job.
