For many of my favourite cold drinks I need crushed ice. That is, thousands of small pieces of ice, not 3 big ice cubes. Is there an easy way to make crushed ice without expensive equipment?
I have not tried this method myself, but it sounds reasonable.
It involves filling a clean milk carton or juice container with water, freezing it and then bashing it against a wall to crush the ice. I guess the container has to be quite sturdy to take the beating without breaking. Could be worth a try.
Search for "Snow Cone Machine" at Amazon.com. The one I linked to is $20.00 (US), does that qualify as "expensive"? Granted, shipping to Cape Town may be a bit higher, but you should be able to find something closer to you than Cleveland, USA. However, at the current exchange rate something in The US might be cheaper for you...
