Instructions
Combine Ingredients:
Pour the heavy cream (or milk), sugar, and vanilla extract into the small ziploc bag. If you're adding mix-ins like chocolate chips or fruit, add them now.
Seal the small bag tightly, ensuring there is no air trapped inside to avoid any leaks.
Prepare the Ice Bag:
Fill the large ziploc bag halfway with ice.
Add the rock salt to the ice. The salt is essential because it lowers the freezing point of the ice, creating a super-cold environment that freezes the ice cream base quickly.
Combine the Bags:
Place the sealed small ziploc bag into the large ziploc bag filled with ice and salt. Make sure the small bag is nestled well within the ice.
Seal the large bag tightly to prevent any leaks during shaking.
Shake It Up:
Shake the bags vigorously for about 5-10 minutes. If the cold gets too intense, wrap the large bag in a towel or wear gloves to protect your hands.
Keep shaking until the mixture in the small bag thickens to an ice cream consistency. This might take a bit of muscle, but it's worth it!
Enjoy Your Homemade Ice Cream!
Serve:
Once the ice cream has thickened, carefully remove the small ziplock bag from the large bag. Wipe off any salt from the outside of the small bag before opening it to avoid getting any salt in your ice cream.
Open the small bag and scoop the ice cream into a bowl or cone. If you want to add any toppings, now's the time!
