Materials:
1 cup sugar (make sure to measure using a dry measuring cup)
1/4 cup water
4 tbs softened butter (salted gives it a great caramel flavor so I recommend it)
1/2 tsp vanilla extract
dash of salt
2 oz bittersweet chocolate, finely chopped
1/2 cup whole roasted, unsalted almonds, chopped
Parchment lined baking sheet
Candy thermometer if you have one
In a small, sturdy saucepan, heat the first 3 ingredients over medium-high heat, stirring until completely combined. At this point, DON'T TOUCH IT LOL :). Let it come to a boil and sit without stirring until your candy thermometer reads 325 degrees. I didn't have a candy thermometer so I just waited until the sugar turned a caramel color. Stir in the vanilla and the salt. Be very careful with this step because the sugar can sputter and there's nothing worse than a sugar burn!
Now, carefully pour your toffee over your baking sheet lined with parchment paper. Try to make a square shape. This will help you keep the candy at a consistent depth throughout the whole piece. Use a knife to spread it out. Let it sit for 5 minutes. Sprinkle your chocolate pieces over the warm toffee and let it sit for 5 more minutes. This will gradually melt the chocolate to the point where you can then spread it evenly over the whole square. Sprinkle your chopped almonds over the melted chocolate then let it sit for an hour or so until the candy is completely cooled. I usually put mine in the fridge so that the chocolate can harden quicker.
To serve, use a knife or any sturdy utensil to hit the toffee and crack it into pieces.
