Step #2 Cool.
Step #3 Stir in the vanilla.
Step #4 Transfer the liquid to a shallow bottomed bowl or square metal cake pan & place this in the freezer.
Step #5 Wait about 30 to 40 mins, then stir the mixture carefully with a wooden spoon, until the sides start to freeze, especially around the edges.
