For those times when you're all out of frozen peas.

Ingredients

• 1 cup rubbing alcohol (70 per cent isopropyl alcohol)
• 2 cups water
• 2 1L freezer bags (make sure they are good quality to prevent leaks)

Method

1. Pour alcohol and water into a freezer bag, remove excess air and seal.
2. Place inside the second freezer bag and remove excess air before sealing.
3. Freeze and use as needed.
4. You can also use some scrap material to sew a cover to act as a barrier from direct contact with the freezer pack.
