2 tablespoons of sugar, a cup of half and half and a teaspoon of vanilla are added to the sandwich bag and the bag is sealed tight. Then the gallon is filled halfway with ice and 1/2 cup salt is added. Then the other bag goes inside and everything is shaken for about five minutes.
C and I took turns shaking the mixture until it was ready. The best thing is it doesn't even need to be put in a bowl when you are done - just eat it straight out of the bag!
C went for plain vanilla (personally I don't understand how a child of mine prefers vanilla over chocolate!) and I added in chocolate and caramel syrups into mine. Yummy!
