Line a plate with parchment paper. You must have it ready, because when the toffee is ready, you need to remove it from the saucepan immediately.
Melt the butter in a small saucepan over medium heat and then add the sugar and salt.
Whisk continuously! Sometimes the toffee separates and / and crumbles, but if you continue to whisk vigorously, it mixes again and you get a smooth mixture that looks like peanut butter. If you use a candy thermometer, it should show 150°C (300°F). This takes about 6 minutes.
Sometimes separated toffee or caramel can be saved by removing the saucepan from the heat and whisk vigorously until it comes back together into a smooth mixture.
Just be careful not to burn it! You don’t want it to turn dark. If you cook it for too long, it will burn and become bitter. But if you do it right, you get dark golden toffee with a buttery and nutty flavor.
Pour the toffee onto the prepared baking sheet, allowing it to spread.
Let cool for about 20-25 minutes.
When its completely cold and hard. Break it into pieces and put it in an electric chopper. Press the button 2-3 times until you are happy with the size of your toffee bits.
