Answers from Expert: Canadian Living Test Kitchen Staff

Generally speaking, if a recipe calls for butter, it's the most common and available butter that's needed, and that's regular salted butter. In Canadian Living recipes we always specify if unsalted butter is required, for example in a butter cream icing where the salt in the butter will interfere with the flavour of the icing. However, you can always use unsalted butter in a recipe created to work with regular salted butter. Just compensate with a pinch of salt.
