My Mum used to make these for School fetes and Church bazaars - they are absolutely sinful and totally divine! They were everyone's favourite, so I used to zoom around beforehand, with my pocket money burning a hole in my pocket, to make sure I bought some before they all went!! A fun name with delicious layers of shortbread, caramel and a chocolate topping. This recipe has the added surprise of adding stem ginger pieces, which was not usual in my Mum's orginal recipe. These do keep for up to a week in an airtight tin or container.....I have never known them last more then 24 hours however - you WILL have to HIDE them!!! They a great for packed lunches and picnics, as well as with afternoon coffee.
