Line a baking sheet with parchment paper and set it down next to the stove.
Place the baking soda in a bowl next to the stove so that it can be thrown in all at once when the time is right.
Add golden syrup, white granulated sugar and water to a medium sized, heavy bottomed saucepan and turn the heat to medium.
Stirring all the while, allow the sugar to melt and begin bubbling away.
Once the mixture begins to boil, attach your candy thermometer and keep stirring vigorously all the while until the mix reaches 300°F (149°C), then immediately move the pot off the heat.
Throw all the baking soda in immediately and stir it in. Be wary as the mix will double or triple in size, so make sure to stir it in with a long handled spoon. Stir it in completely but don't overmix or your mixture will start to deflate.
Pour the mix out onto the parchment lined baking sheet and leave it be. Don't try to smooth it out, once it's poured just leave it to take the shape it wants to take.
Leave it to cool down and set. This will take at least an hour.
When it's completely set, break it into pieces.
Add vegan chocolate and coconut oil to a microwave safe bowl and melt it by microwaving it in 30-second intervals in the microwave, bringing it out to stir every 30-seconds until melted.
Roll the honeycomb pieces in the melted chocolate and then place them back onto the parchment lined baking sheet.
Place the tray into the fridge for the chocolate to set and then your vegan honeycomb is ready to serve!
