This recipe produces a professional-grade, glass-like snap that makes it an irresistible snack or a stunning gift for any occasion.
🥗 Ingredients
The Nut Base
- 2 cups Raw Cashews (halves or whole, unsalted)
- 1/2 teaspoon Sea Salt (fine grain)
The Toffee Syrup
- 2 cups Granulated Sugar (white cane sugar)
- 1 cup Light Corn Syrup (to prevent crystallization)
- 1/2 cup Water (filtered)
- 4 tablespoons Unsalted Butter (cubed, at room temperature)
The Finishers
- 1.5 teaspoons Baking Soda (sifted to remove lumps)
- 1.5 teaspoons Vanilla Extract (pure Madagascar vanilla preferred)
- 1 teaspoon Flaky Sea Salt (for topping)
- 1/4 teaspoon Ground Cinnamon (optional, for warmth)
👨🍳 Instructions
-
1
Prepare your workspace by lining a large rimmed baking sheet with a silicone baking mat or heavily buttered parchment paper. Set it on a heat-proof surface.
-
2
In a small bowl, pre-mix your baking soda, vanilla extract, and cinnamon (if using). Having these ready is crucial as the final stage moves very quickly.
-
3
In a heavy-bottomed 3-quart saucepan, combine the granulated sugar, light corn syrup, and water. Stir over medium heat until the sugar dissolves.
-
4
Clip a candy thermometer to the side of the pan, ensuring the bulb is submerged in the liquid but not touching the bottom of the pot.
-
5
Bring the mixture to a boil. Once boiling, stop stirring. Cook the syrup until the thermometer reaches 250°F (121°C), which is the 'hard ball' stage.
-
6
Stir in the raw cashews and the cubed butter. The temperature will drop slightly; continue to cook, stirring constantly now to prevent the nuts from scorching.
-
7
Continue cooking and stirring until the mixture reaches 300°F (149°C), known as the 'hard crack' stage. The syrup should be a beautiful light golden brown.
-
8
Immediately remove the saucepan from the heat. Working quickly, stir in the baking soda/vanilla mixture. The candy will foam up and become aerated and lighter in color.
-
9
Quickly pour the foaming mixture onto the prepared baking sheet. Do not scrape the bottom of the pan too aggressively, as scorched bits may be stuck there.
-
10
Using a heat-resistant spatula, lightly spread the brittle toward the edges of the pan to about 1/4 inch thickness. Do not over-work it, or you will lose the air bubbles.
-
11
While the brittle is still tacky, sprinkle the flaky sea salt evenly over the top for that perfect sweet-and-salty finish.
-
12
Allow the brittle to cool completely at room temperature for at least 45-60 minutes until it is hard and stone-cold.
-
13
Once cooled, lift the brittle and crack it into irregular, bite-sized shards using your hands or the handle of a butter knife.
💡 Chef's Tips
Always use a candy thermometer for precision; even 5 degrees can change the texture from chewy to snappy. Avoid making brittle on a humid or rainy day, as the sugar will absorb moisture from the air and become sticky. Sift your baking soda before adding it to ensure there are no bitter white clumps in your finished candy. Warm your cashews in the oven at 200°F for a few minutes before adding them to the syrup so they don't shock the temperature of the sugar. Store in an airtight container with parchment paper between layers to maintain the crisp 'snap'.
🍽️ Serving Suggestions
Serve alongside a glass of aged Bourbon or a smoky Scotch to complement the toasted nut flavors. Crush smaller fragments and sprinkle over premium vanilla bean ice cream or salted caramel gelato. Include shards on a dessert charcuterie board with dried apricots, dark chocolate squares, and sharp cheddar cheese. Package in cellophane bags with a gold ribbon for a sophisticated homemade holiday gift. Pair with a hot cup of dark roast coffee or a spicy chai latte.
