Roxanne’s Millionaire’s Shortbread

This is the recipe, given to me by a fellow-mother at my daughter’s school, that introduced me to the notion of melting chocolate in the microwave. I am now a complete convert: it is truly the best way to do it. And you make the caramel in the microwave, too, so what would normally take a good couple of hours takes only a few minutes. Another revelation. It’s not that I had never used a microwave before, but I hadn’t ever realized it could do things better as opposed to just faster.
