No special equipment is needed for this recipe with the exception of a candy thermometer. Yes, you can make it without the thermometer but unless you understand what caramel looks and smells like at the hard-crack stage, you may not achieve the crispiness that makes this so special.

Boiling sugar brings me back to my days in pastry school. I have this image in my head of 14 students leaning over induction units, pots filled with boiling sugar, staring at candy thermometers. It seems like the second you glanced away your thermometer would go haywire and, voila, ruined sugar. Today I can usually tell what stage I’m at in the sugar cooking process without a thermometer. But old habits die hard and you can still find me staring at my thermometer while working with sugar!

Tips for Making the Perfect Nut Brittle

  • Ingredients:
    • What type of nuts to use in this recipe? Whatever you want! My family and friends like this treat best when I use mixed nuts and throw in extra pistachios for a bit of color. Prefer all peanuts? Not a problem, just use 12 ounces of peanuts.
  • Creating the Brittle:
    • Before starting the caramel prepare your area where you will be spreading the caramel. You may use a Silpat or parchment-lined cookie sheet or lightly butter a cookie sheet. You want this near your work area as you need work quickly once the nuts are added to the caramel.
    • The caramel is cooked to the hard-crack stage, which is 300°. Do not allow the candy thermometer temperature reader to touch the bottom of your pan as this will cause an inaccurate measurement. Place the tip about halfway into the syrup.
    • Once the syrup reaches 300°, which will take 8 – 12 minutes, stir in the baking soda. Use caution as the syrup is quite hot and can cause sever burns if you spill it on yourself.
    • Next, working quickly, stir in the nuts to coat with the caramel.
    • Immediately spread on your prepared cookie sheet using a spatula. Allow to cool completely (about 40 minutes) and break into the size pieces you desire.
  • Storing Your Creation:
    • This treat is filled with sugar which is quite hydroscopic, meaning it will absorb the moisture from the air around it. If this occurs you will have a sticky brittle. Place the brittle pieces in an airtight container and store in a cool, dark area. It will last for approximately a month if stored properly.
