Step 1

In a wide mouth pint-sized mason jar, combine heavy cream, sugar, vanilla, and salt, plus any additional flavor variations you plan to use. (Things like chocolate chips, nuts, and fruit should be stirred in later.)

Step 2

Close jar lid and shake. At about five minutes, open jar and dip a spoon into the mixture. Liquid should have doubled in size and mixture should be the consistency of a runny cake batter.

Step 3

Cover jar and place in freezer. Shake every 30 minutes to continue aerating, ice cream will be ready in 2-3 hours. Enjoy!
