In a small pot over medium heat, use a whisk to combine all ingredients except for the bicarbonate*
Bring to a boil, and dissolve the sugar, whisking occassionally
Continue boiling, evaporating off the water, adjusting the heat so that it doesn't boil too rapidly
While the mixture is boiling, sift the bicarbonate in a small bowl, and prep a small baking tray by completely lining it with parchment paper
Once the sugar solution reaches 150°C (302°F), remove from the heat and quickly whisk in the bicarbonate. Make sure you whisk enough that you aren't left with pockets of baking soda, but not too long or you'll deflate it
Immediately pour the honeycomb into your prepared pan, being gentle so as not to deflate the mixture. Don't be tempted to touch the surface while scraping in the last bits, or you'll end up deflating it
Allow to cool (the surface will be hard) then break into small pieces and store in an airtight container
*make sure the pot isn't too small, as the baking soda reaction grows a lot!
