This is the easiest, best toffee I have ever made. Everyone who tries it wants the recipe.
Achieving the correct temperature (300°F/150°C) is crucial for toffee. A candy thermometer is non-negotiable for success; undercooking results in soft, chewy candy, while overcooking yields a burnt taste. Stir constantly until boiling to dissolve sugars and prevent crystallization. Once boiling, resist stirring to avoid sugar crystals forming on the sides. Prepare your dish with nuts and chocolate *before* you start cooking, as the process moves quickly. Ensure chocolate chips are evenly distributed to melt smoothly from the residual heat. For a cleaner break, allow the toffee to cool completely, ideally at room temperature for several hours or briefly in the refrigerator, before breaking into pieces. A light salting with flaky sea salt on top can elevate the flavor profile.
