📝 About This Recipe

Experience the culinary magic of chemistry with this classic British confection, known for its dramatic 'volcano' rise and airy, sponge-like interior. This brittle, amber-hued candy shatters into a thousand shards of deep caramel and toasted honey notes before melting away on the tongue. It is a nostalgic masterpiece that relies on the perfect balance of heat and aeration to create its signature bubble-filled architecture.

🥗 Ingredients

The Sugar Base

  • 2 cups Granulated white sugar (high quality for even melting)
  • 1/2 cup Golden syrup (can substitute with light corn syrup if unavailable)
  • 2 tablespoons Honey (clover or wildflower for floral depth)
  • 1/3 cup Water (filtered)
  • 1/4 teaspoon Cream of tartar (helps prevent crystallization)

The Aeration Agent

  • 1 tablespoon Baking soda (sifted to ensure no lumps)

Flavoring and Finishing

  • 1 teaspoon Pure vanilla extract (add at the very end)
  • 1/2 teaspoon Flaky sea salt (for sprinkling)
  • 4 ounces Dark chocolate (70% cocoa, melted for dipping)
  • 1 teaspoon Unsalted butter (to grease the parchment paper)

👨‍🍳 Instructions

  1. 1

    Prepare a 9x9 inch deep baking pan by lining it with parchment paper, ensuring the paper hangs over the edges for easy removal. Lightly grease the parchment with a small amount of butter.

  2. 2

    Sift your baking soda through a fine-mesh strainer into a small ramekin. It is vital that there are no lumps, as they will create bitter pockets in your finished candy.

  3. 3

    In a heavy-bottomed, deep saucepan, combine the sugar, golden syrup, honey, water, and cream of tartar. The pot must be much larger than the ingredients, as the mixture will expand significantly later.

  4. 4

    Stir the mixture over medium-low heat until the sugar has completely dissolved. Use a wet pastry brush to wash down any sugar crystals clinging to the sides of the pot.

  5. 5

    Once the sugar is dissolved, clip a candy thermometer to the side of the pot and increase the heat to medium-high. Do not stir the mixture from this point forward.

  6. 6

    Boil the syrup until it reaches exactly 300°F (149°C), also known as the 'hard crack' stage. This usually takes 8-12 minutes depending on your stove.

  7. 7

    As soon as the thermometer hits 300°F, immediately remove the pan from the heat. Carefully whisk in the vanilla extract (watch out for steam!).

  8. 8

    Working very quickly, dump the sifted baking soda into the center of the pot. Whisk vigorously for about 3-5 seconds until the mixture foams up into a thick, pale gold 'volcano'.

  9. 9

    Stop whisking immediately—over-mixing will deflate the bubbles. Pour the foaming mass into the prepared baking pan. Do not spread it or smooth the top; let it settle naturally.

  10. 10

    While the candy is still hot and tacky, sprinkle the flaky sea salt evenly over the surface.

  11. 11

    Allow the honeycomb to cool completely at room temperature for at least 1-2 hours. Do not refrigerate, as the moisture will make it sticky.

  12. 12

    Once hardened, lift the parchment paper to remove the slab. Use the handle of a knife or your hands to crack it into rustic, jagged shards.

  13. 13

    Optional: Melt dark chocolate in a double boiler and dip half of each shard into the chocolate. Place on wax paper to set.

💡 Chef's Tips

Always use a deep pot; the mixture will quadruple in size when the baking soda is added. Humidity is the enemy of honeycomb—make this on a dry day for the best, crunchiest results. Don't walk away from the stove; sugar temperatures rise very rapidly once they pass 270°F. If you don't have a thermometer, the syrup should be a light amber color, similar to a copper penny, before adding the soda. Store immediately in an airtight container to prevent the sugar from absorbing moisture from the air.

🍽️ Serving Suggestions

Crumble small pieces over high-quality vanilla bean ice cream for a textural contrast. Serve alongside a bitter espresso or a dark roast coffee to balance the intense sweetness. Use shards as a dramatic garnish for a salted caramel layer cake. Package in cellophane bags with a ribbon for a sophisticated homemade gift. Pair with a sharp blue cheese and green apple slices for a unique dessert board.
