Do you need eggs to make homemade ice cream in a bag?

The traditional "ice cream in a bag" method relies on the freezing point depression of salt and ice. The salt lowers the freezing point of the ice, causing it to melt more rapidly. This melting absorbs heat from the surrounding environment, including the ice cream mixture, causing it to freeze.

Eggs are traditionally used in ice cream to provide richness and a smooth texture. However, they aren't necessary for the basic ice cream in a bag process.

Here's a basic recipe that doesn't use eggs:

Ingredients:

* 1 cup heavy cream

* 1/2 cup milk

* 1/4 cup sugar

* 1/2 teaspoon vanilla extract

Instructions:

1. Combine all ingredients in a resealable plastic bag.

2. Place the bag inside a larger resealable plastic bag.

3. Fill the outer bag with ice and add a generous amount of salt.

4. Seal both bags tightly and shake vigorously for 10-15 minutes until the mixture is frozen.

5. Enjoy!

You can always add other ingredients like chocolate chips, fruit, or nuts to your liking.
