I'm thinking of buying a blender for making smoothies. Is it OK to crush ice in a blender with a plastic jug, or will I be better off with a (more expensive) glass one? Many thanks!
blenders don't really crush ice very well in my experience. I don't think a plastic or glass container will make much difference. I would suggest putting the ice in a plastic bag and hitting it a few times with a rolling pin to crack it into smaller pieces, THEN putting it in the blender for the best results.
The issue is not glass or plastic but the quality of the motor - the higher the wattage the better really. As a rule the better quality blenders will have glass jugs anyway. As long at the blender has an "Ice" setting where the blades pulse then you should be fine.
