Grease a 9x13 baking tray, the wrappers from the sticks of butter work great for this.
Place the butter in a sauce pan over low heat.
225 grams Butter
Once the butter is halfway melted, add the sugars, water, and honey and stir to combine until fully incorporated.
125 grams White Sugar, 140 grams Brown Sugar, 3 tbsp Honey, 2 tbsp Water
Clip the candy thermometer to the side of the sauce pan and turn heat up to medium low. The mixture will start to bubble and turn brown as it cooks. If the mixture seems to be cooking unevenly, you can swirl the mixture in the pan by tilting it around but do not stir with a utensil.
Once the candy thermometer reads just under 150 Celsius, about 10-15 minutes, remove the pan from the heat and remove the thermometer and stir in the vanilla and salt. Once combined pour mixture into the greased 9x13 pan.
1 tsp Vanilla Extract, 1/2 tsp Kosher Salt
Once the mixture has evened out in the pan, leave to cool for one minute and then sprinkle the chopped chocolate over the top of the toffee and wait for it to melt, around 3 minutes. Use the offset spatula to spread the chocolate evenly over the top of the toffee.
225 grams Dark Chocolate (60-72%)
Sprinkle the almonds over the top of the chocolate and gently press the almonds into the chocolate so that they stick.
150 grams Roasted Almonds
Cover the toffee and freeze for 30 minutes or until firm.
Remove from freezer and break toffee into pieces with a knife. Store toffee in a cool place for up to a week.
