Make the vanilla frosting:
  1. Bring two inches of water to simmer in bottom of double boiler then in top of double boiler. Combine the sugar, egg whites, water, cream of tartar, syrup and salt.
     
  2. Beat with electric mixer (about 7 minutes) on high- it will quadruple in volume and become shiny and form peaks.
     
  3. Remove from heat and add the vanilla paste.
     
  4. Continue to beat 2 minutes longer and use immediately.
