Tips
Use a candy thermometer for accuracy; the difference between 290 and 300 degrees determines whether your toffee is chewy or brittle.
Have all ingredients measured and ready before starting; the cooking process moves quickly once sugar reaches boiling.
Press nuts into chocolate while still warm so they adhere firmly as it cools.
Good to Know
Keep in airtight container at room temperature for up to 2 weeks. Layer between parchment paper to prevent sticking.
Make up to 1 week ahead. Store in airtight container in cool, dry place.
Serve at room temperature. Break into pieces or cut with a knife lightly oiled.
Common Mistakes
Do not stir vigorously once mixture reaches boiling to avoid crystallization.
Do not walk away from stove during cooking to prevent burning.
Do not skip the thermometer to avoid undercooking or burning the batch.

FAQ
Can I make this without a candy thermometer?
A thermometer ensures accuracy, but you can use the cold-water test: drop a small amount into ice water. At 290 degrees it breaks cleanly. This method is less reliable and risks burning or undercooking.
What if my toffee turned out chewy instead of crisp?
The mixture did not reach 290 degrees. Next time, cook longer and monitor the thermometer closely. If it crystallizes, start over; reheating won't fix it.
How long can I keep toffee?
Properly stored in an airtight container at room temperature, homemade toffee keeps 1-2 weeks. Humidity makes it soften faster, so store in a cool, dry place away from direct heat or sunlight.
