4 Tbsp. meringue powder
1/2 scant cup water
1/2-1 tsp. corn syrup
few drops of clear extract (I use almond)
1 lb. sifted powdered sugar.
With your paddle attachment mix the meringue powder and water, then add in the powdered sugar. Once those are incorporated add the extract and corn syrup. Mix on med-high for about 5 minutes or until stiff peaks form.
The icing can now be thinned 1 tsp at a time until desired consistency is reached.
