butterscotch a very crisp form of toffee containing butter, and sometimes also milk or cream. The quantity of butter in formulae used by various manufacturers differs, but, by law, any product made in the UK which includes the word ‘butter’ in the name must contain at least 4 per cent butterfat in the finished item. Salted butter is usually stipulated, and oil of lemon added as a flavouring.
The origin of the name is unknown, but it does not appear to have any direct link with Scotland.
