This is a classic millionaire's shortbread. I prefer a thin shortbread base, because it provides full flavor without the dryness. The caramel, made with evaporated milk, is smooth and holds its form. The topping is a simple semisweet chocolate that adds a nice crunch once hardened. And, of course, a generous sprinkling of sea salt is essential.
