The first thing you will need to do is gather all of the items that you need. To make plastic baggy ice cream you will need the following; sugar, half and half, salt; rock salt works best, vanilla, ice cubes; enough to fill half of the gallon size bag, one pint size Ziploc bag, and one gallon size Ziploc bag. After all of your items are gathered, the sugar, half and half, and salt will all have to be measured out. You will need two tablespoons of sugar, a half teaspoon of vanilla, one cup of half and half, and a half a cup of salt.
Once everything is gathered, measured, and ready to go, it is time to get started adding everything together. The first thing you will want to do is open your small, pint size plastic baggy. Next you will want to combine your sugar with the half and half and vanilla all in the plastic bag. Once everything is in the baggy, make sure it is closed and sealed tight. Afterwards, you will need to get the gallon size bag ready. Open your gallon Ziploc bag and fill it about half full with ice. Once the ice is in the baggy, add the half cup of salt right into the gallon bag, over the ice. Before you close your bag, place the sealed, pint size bag in along with the salt and ice. When the pint size bag has been placed into the gallon size, seal the gallon size back tight. After everything is combined into the right baggies and they are sealed tight, it is time to shake.
It should take about five minutes or so of continuous shaking to start seeing the difference of the liquid turning into the solid. You want to shake the gallon size bag really well until you can feel the mixture of things in the pint size bag starting to get ice cream textured. Immediately following the shaking of the bag and the pint size bag is starting to harden, carefully open the gallon size bag. Make sure to open the bag carefully because you do not want the ice falling out. Once you have opened the bag, pull the pint size bag out of the gallon size bag. Your ice cream is now ready to eat! You will usually have a single serve size or two serving sizes.
In the end, you can add whatever mixings you want to; sugars, sprinkles, chocolate sauce, etcetera. Making ice cream at home is not hard at all and there are only a couple of supplies needed in order to do so! Furthermore, making plastic bag ice cream is a great activity to do especially with kids! It is a fun way to get your children and their friends involved with making their own ice cream and learning measurements. It is a very simple activity. It also gives you a free, all access pass to the delicious treat you love, as well as an easy clean up! All there is to do in the end is simple, dump the ice out of the gallon baggy and throw both bags out.
