Sweet-and-Salty Nut Brittle

This caramelized nut brittle is a bit addictive. Nearly any nut can be a candidate for a one-nut version, but a mixture of nuts, or even seeds, like sesame or pumpkin, makes it more interesting, and a final sprinkling of sea salt adds an especially pleasing note. Break off pieces to serve as after-dinner sweets or with tea or coffee. It can also become a dessert topping, coarsely crushed and crumbled over ice cream.
