stable boiled icing

Step 1

Combine sugar, water, corn syrup, and salt in a saucepan and stir the mixture until well blended.

Step 2

Boil slowly without stirring until mixture spins a long thread when a little is dropped from a spoon.

Step 3

In a large bowl, beat egg whites until they are stiff but still moist. Pour hot syrup slowly over egg whites while beating.

Step 4

Continue until mixture is very fluffy and will hold its shape.

Step 5

Add vanilla extract and beat until blended.

Step 6

If icing does not seem stiff enough, beat in two or three tablespoons confectioner’s sugar, one tablespoon at a time, until it’s stiff enough to hold its shape. Spread on the cake.
