Pralines and Nut Brittle
These candies sit at the intersection of patience and precision. Get the sugar temperature right and you have candy. Miss it by 5 degrees and you have either soft taffy or a rock.
Temperature is everything — use a reliable candy thermometer
Sugar syrup changes state in a narrow window. At 300°F it's hard crack. At 310°F it's starting to burn. A digital thermometer or a clip-on analog thermometer is not optional. Also: work on a marble slab or a buttered sheet pan. Once the sugar sets, you're done shaping.
- candy thermometer (digital or clip-on analog)
- heavy-bottomed saucepan (2–3 quart)
- wooden spoon (heat-resistant)
- marble slab or buttered sheet pan
- offset spatula or bench scraper
- kitchen scissors (for cutting while warm)
What goes in.
- 2 cupsgranulated sugar
- ½ cupwater
- ½ cuplight corn syrup
- 3 tablespoonsunsalted butter
- 1 teaspoonvanilla extract
- ½ teaspoonfine sea salt
- 2 cupsroasted, unsalted nuts (pecans, almonds, or peanuts)
- ¼ teaspoonbaking soda (for brittle only)
Watching the sugar change color without moving it
Once the mixture reaches 240°F, resist the urge to stir. The sugar is turning amber from the outside in, and stirring disrupts that. Swirl the pan gently if you need to even the heat, but don't scrape or stir. When it hits hard crack (300–310°F), you'll see deep amber—almost tea-colored. That's the moment you work with it.
The method.
Combine sugar, water, and corn syrup in the saucepan.
Stir over medium heat until the sugar dissolves. Once it starts boiling, stop stirring. Clip the thermometer to the side of the pan so the bulb sits in the syrup, not touching the bottom.
Let the mixture cook without stirring until it reaches 300–310°F.
This takes about 10–12 minutes. The syrup will go from clear to pale yellow to amber. At 300°F, it's ready for brittle. At 310°F, it's where you want to be for pralines. If it goes past 320°F, it will taste burnt. Watch it closely once it hits 280°F.
Remove from heat and add butter, vanilla, and salt.
Stir gently to combine. The mixture will bubble slightly as you mix. For brittle, add the baking soda now—it will foam and lighten the texture. Stir it in.
Add the nuts and stir quickly until coated.
Work fast. The sugar is setting even as you stir. You have roughly 30 seconds to get the nuts evenly coated before it stiffens up.
For brittle: pour the mixture onto a buttered sheet pan and spread thin with an offset spatula.
Work quickly. Once it stops flowing, you're done shaping. Let it cool completely—about 20 minutes. Break into pieces with your hands. For pralines: drop spoonfuls onto a buttered sheet pan as the mixture cools slightly, shaping each with the back of a spoon into a rough disc.
Other turns to take.
Pecan Brittle with Sea Salt
Use roasted pecans and increase the sea salt to ¾ teaspoon. The salt sharpens the caramel flavor and cuts through the richness.
Almond Brittle with Orange Zest
Add 1 tablespoon of finely grated orange zest to the syrup at 280°F, before the nuts. The citrus mellows the caramel.
Rum Pecan Pralines
Substitute 1 tablespoon of dark rum for ½ teaspoon of the vanilla. Add it after removing from heat. Use pecans and drop as small pralines onto parchment.
Chocolate-Dipped Brittle
Once the brittle has cooled and broken, melt 6 oz of dark chocolate and dip one edge of each piece. Set on parchment to cool.
When it doesn't go to plan.
Humidity matters. On a dry day, the candy will harden faster and stay crisp. On a humid day, cover finished candy in an airtight container within a few hours, or it will weep and soften.
If the sugar crystallizes (turns grainy and dull), start over. This usually happens from stirring too much or from a grain of sugar on the side of the pan. Use a wet pastry brush to wipe down the sides before it boils.
Nuts should be room temperature, not cold from the fridge. Cold nuts can shock the hot sugar and cause it to seize.
The moment the mixture leaves the heat, it's still working. Don't taste it—it will be hot enough to blister your mouth.
If brittle hardens before you finish spreading, return it to low heat for 30 seconds to soften it again.
The ones that keep coming up.
Can I use a candy thermometer on the stovetop or do I need to clip it?
Either works, but a clip-on keeps it stable and in the right position. An unclamped thermometer can tip into the syrup or rest on the bottom of the pan, giving false readings. If you use an unclamped one, hold it steady with your hand or wedge it carefully against the rim.
What if my brittle turns out chewy instead of crispy?
You stopped cooking it too early. Hard crack for brittle is 300–310°F, closer to 310°F. Soft crack (270–290°F) makes chewy candy. Next time, let it go a few more degrees. If this batch is still warm, you can reheat it and cook it hotter.
My pralines spread and flattened instead of staying as mounds. What happened?
The sugar was still too hot when you spooned it out, or the pan was too warm. Next time, let the mixture cool for 1–2 minutes after adding the nuts, and use a cool (or room-temperature) sheet pan. The mixture should hold its shape when dropped.
Can I use salted or roasted nuts?
Yes to roasted, but be careful with salted. If your nuts are already salted, reduce the salt in the recipe to ¼ teaspoon to avoid over-salting the finished candy.
How long does brittle or pralines keep?
In an airtight container at room temperature, about 2 weeks. In the fridge, a month. They will absorb moisture and soften if exposed to air or humidity, so seal them tight.
