Spring this on the kids (or office gang) on that day in August when everyone is grumpy and no one wants to anything.

Ingredients:

• 1 c half and half
• 2 Tab sugar
• 1/2 tsp vanilla extract
• Any of your favorite ice cream mix-ins
• 1 pint-size Ziploc bag
• 1 gallon-size Ziploc bag
• ice cubes
• 1/2 c Kosher salt

Directions:

1. Combine the half and half, sugar and vanilla extract in the pint-size bag.
2. Seal the bag tightly, so that none of the liquid will leak out.
3. Fill the gallon-size Ziploc bag halfway with ice cubes.
4. Sprinkle Kosher salt over the ice cubes.
5. Insert the pint-size bag filled with ingredients into the bag of ice and salt.
6. Seal the gallon-size Ziploc bag.
7. If the bag begins to leak, don’t hesitate double bagging it to reduce the mess.
8. Shake the bag for 5-10 minutes until the ice cream mixture begins to harden. Feel the small bag to determine the consistency of your ice cream.
9. Once satisfied with the consistency, remove the small bag from the bag of ice.
10. Open the small Ziploc bag and add any desired mix-ins that you want.
11. Feel free to eat the ice cream right out of the bag or, if you prefer, scoop it into a bowl.
12. Enjoy!
