Ice cream in a bag

Ice cream in a bag

Did you know making ice cream can be as easy as shaking a bag of ingredients? The hardest part is deciding what flavour your ice cream will be!

Equipment and ingredients:

Measuring jug
1 medium zip lock bag
2 large zip lock bags

2 trays of ice cubes (or 4 good handfuls)
6 tablespoons regular table salt
200mls cream
100mls dark blue top milk
2 tablespoons caster sugar
Flavouring of your choice

Failsafe method:

1. Measure out 200mls of cream and 100mls of milk.
2. Pour both into the smaller of the zip lock bags.
3. Add caster sugar to the cream mixture.
4. Add your choice of flavours to the smaller bag.
5. Remove the air and seal the bag (make sure you close it carefully!).
6. Measure 6 tablespoons of table salt into the larger bag and add the ice.
7. Place the sealed smaller bag (with the cream mixture) inside the larger bag.
8. Double-check BOTH bags are sealed tightly.
9. Now - shake, shake shake. When your arms get tired, pass to the next person to help out (it will take at least 5 minutes of non-stop shaking).
10. Give the bag a squeeze and check to see that it has changed into ice cream. If not..... keep shaking!
11. Eat and enjoy.

The science of ice cream

This ice cream recipe comes from a science lesson with a twist that's part of DairyNZ's in-school education programme. The twist was to find out if you could have a breakfast flavoured ice cream!

Schools all across the country took part, and as well as experimenting with flavours like Marmite, baked beans, cornflakes and honey, they also got to grips with the science behind making ice cream.
