Coles’ list of ingredients does not include vanilla (and I would be surprised if it did, given that this is the cut-price version of their cut-price ice cream.
Agreed, except there are some items (such as meats and onions) I prefer to put in a plastic bag as they can leak - and the plastic bags are more easily cleaned.
