1 egg white, chilled
1 c. sugar
1/4 tsp. cream of tartar
1/2 c. boiling water
1/2 tsp. vanilla

Combine egg white, sugar, and cream of tartar in large bowl. Add boiling water. Begin at once to beat with electric mixer. Continue beating on high speed until thick and fluffy and mixture stands in stiff peaks. Add vanilla. Frosts one 2- layer cake. (This is a good recipe for piping into chocolate cupcakes for cream-filled treats.)
