Place ingredients in a small, shallow saucepan set over medium heat/flame. Let sit on flame, poking occasionally as the sugar begins to heat and melt, so as to avoid over-burning certain areas. This “poking” stage will last around 3–5 minutes.
When sugar begins melting into syrup, begin to stir constantly and be sure to coat all Nature's Eats Macadamia Nuts entirely. The syrup will quickly turn to a very thin liquidy state, which is desired, and begin to bubble and smoke. A candy thermometer can be used to check the temperature, which should come to around 300F (very hot) at this hard crack stage of candy making. At this stage, remove from flame and pour with care onto a prepared sheet of wax paper. Shaping the candy must be done immediately, while the sugar is still hot and malleable. A wooden spatula should be used, as plastic utensils will melt at contact. We like to create it into a circle as topping for cakes.
Once shaped, let it sit until cool to touch – again, we cannot stress enough, it is VERY hot! Once cooled to touch, cut the brittle into smaller, decorative pieces – put the whole brittle in an oven to warm a bit, then slice into preferred shapes.
Though any nuts may be substituted to your preference, that they are raw is vital! If already salted or roasted, they will burn in cooking. High temperatures are required to candy the sugar, and much caution should be used in making and handling this recipe. Makes an elegant topping to a round cake, or great as a lone treat.
