Step 1: Line Your Pan

Start by lining a baking sheet with parchment paper or a silicone baking mat. Set it aside but keep it close, as you’ll need to act fast once the candy is ready.

Step 2: Heat Sugar, Syrup & Water

In a heavy-bottom saucepan, combine sugar, corn syrup, and water. Stir gently until the sugar is moistened. Place over medium heat and stop stirring once the sugar has dissolved.

Allow the mixture to boil until it reaches 300°F (hard crack stage) on a candy thermometer. This usually takes about 5–10 minutes. Keep a close eye to prevent burning.

Step 3: Add Baking Soda

Once the mixture hits 300°F, immediately remove it from heat. Quickly and carefully whisk in the sifted baking soda. The mixture will foam up vigorously—this is exactly what you want! Stir just until the baking soda is fully incorporated (1–2 seconds).

Step 4: Pour and Let It Set

Immediately pour the foamy mixture onto your prepared baking sheet. Do not spread or touch it—this will collapse the bubbles. Let it spread naturally and cool completely, about 1 hour at room temperature.

Step 5: Break Into Pieces

Once fully hardened, use your hands, a knife, or a mallet to break the honeycomb into bite-sized chunks. Store in an airtight container to preserve its crunch.
