Instructions

See attached PDF

If you have someone with a dairy allergy or intolerance - this can also be made using fruit juice instead of milk to create a sorbet.

Copied from the attached PDF:

1. Pour half a cup of flavoured milk into the small zip-lock bag and seal it tight

2. Put a generous amount of ice into the large zip-lock bag, then add 6 tablespoons of salt. The salt lowers the freezing point of the ice, and you will see the ice begin to melt.

3. Place the small zip-lock bag inside the large bag with the ice and salt, and seal the large bag.

4. Put on some gloves (so your hands don’t get cold) and start to gently shake and squeeze the bag.

5. After five minutes of shaking, carefully take the small bag out and taste your ice cream!

Top tip: Be careful not to spill any of the salty ice water or mix it with your ice cream as you get it out of the bag.
Top tip two: if your ice cream doesn't get hard enough for your liking, stick it in the freezer
