Line a baking sheet with parchment paper and set aside.
Add the sugar and honey to a heavy-bottomed saucepan. Heat gently and stir until combined. Once the mixture starts to boil, stop stirring. Stay close and wait until the caramel turns an amber color.
Add the baking soda and stir quickly. Pour the hot mixture onto the prepared baking sheet and let it sit undisturbed.
Once the honeycomb has cooled completely, cut it into pieces with a sharp knife or break it into chunks.
Tips
Caution: Do not touch the caramel or honeycomb while hot, you don’t want to burn your fingers. Let it cool completely first.
You can also use a candy thermometer; aim for a temperature of about 300°F (150°C).
