this recipe on Mother's Day as our first science experiment on family day. Mike was very leary as he watched us furiously shaking Ziplock baggies expecting ice cream. Then, as soon as he saw the results, he threw the kids in the car and went out to buy more half and half and a new bag of ice. We made it again when his family came over for dinner that night.
Just so you don't throw all of the ingredients together, here is what you will need to make homemade ice cream in a baggie...
In the pint-sized Ziploc bag:
2 Tablespoons sugar
1 cup half & half (or light cream)
1/2 tsp vanilla extract
In the gallon-sized Ziploc bag:
1/2 cup coarse salt
Mix the sugar, half & half and vanilla extract together. Pour into a pint-sized Ziploc baggie. Place the small bag inside the large bag, fill it half-way with ice and add the 1/2 cup salt.
Make sure each bag is sealed tightly and start shaking. Shake for about 5 minutes (or 8 minutes if you use heavy cream.) Open the gallon-sized bag and check to see if the ice cream is hard, if not keep shaking.
