📖 Instructions

1. First off, get everything ready. Line a 9x13 inch baking sheet with parchment paper. Make sure the parchment extends up the sides a bit for easy handling. Set aside about half of your chopped almonds (for mixing into the toffee) and the other half for sprinkling on top. Have your candy thermometer clean and ready to go.
2. In a heavy-bottomed 3-quart saucepan, combine the granulated sugar, unsalted butter, water, and salt. A heavy-bottomed pan is super important here; it helps distribute heat evenly and prevents scorching.
3. Place the saucepan over medium-high heat. Stir constantly with a wooden spoon or heat-proof spatula until the butter melts and the sugar completely dissolves. This is crucial for avoiding a grainy texture later on. You should see the mixture turn clear and bubbly.
4. Once the mixture comes to a rolling boil, stop stirring. Insert your candy thermometer, making sure it doesn't touch the bottom of the pan. Let the mixture boil, carefully watching the temperature. The color will start to change from light yellow to a beautiful golden amber.
5. When the mixture reaches 280°F (138°C), quickly stir in the first half of the chopped almonds. Stir just enough to incorporate them. Don't overmix!
6. Continue cooking, without stirring, until the thermometer reads 300°F (149°C). This is the "hard crack" stage, where your toffee will be perfectly crisp. If you go a little over, say to 305°F (152°C), it's okay, but don't let it burn. The color should be a rich, deep amber.
7. Immediately remove the saucepan from the heat. Carefully and quickly pour the hot toffee mixture onto your prepared baking sheet. Use the back of your spoon or spatula to gently spread it into an even layer, if needed. Work fast, as it sets quickly!
8. Let the toffee cool on the baking sheet for about 5-10 minutes. It should still be warm to the touch but starting to firm up.
9. While the toffee is cooling, melt your chocolate chips. You can do this in a microwave-safe bowl in 30-second intervals, stirring between each, or over a double boiler. Make sure it's smooth and lump-free.
10. Pour the melted chocolate over the slightly cooled toffee and spread it evenly with an offset spatula or the back of a spoon.
11. Immediately sprinkle the remaining chopped almonds over the melted chocolate. Gently press them down a little so they adhere.
12. Let the toffee cool completely at room temperature for at least 1 hour, or place it in the refrigerator for about 30 minutes, until it's completely firm and the chocolate is set. Patience here is key!
13. Once fully set, lift the parchment paper from the baking sheet. You can either use a sharp, heavy knife to carefully score and break the toffee into pieces, or for a more rustic look (which I often prefer!), place the sheet on a solid surface and gently tap it with a small hammer or the back of a rolling pin. Break it into irregular, bite-sized pieces.
14. Your glorious homemade almond butter toffee crunch is ready! Enjoy immediately or store in an airtight container.
