In a small saucepan (not over heat) combine the sugar and golden syrup.

Place the pot on low-medium heat and heat the mixture until golden. Do no stir it but you can swirl the pan so it all heats evenly.

When the mixture is golden, remove the saucepan from the heat and quickly whisk in the bi-carb soda. Whisk just until it starts to froth then quickly pour the mixture out onto a baking paper lined tray or a silicone baking mat.

Leave it to set (pop it in the fridge if you're in a hurry or it's humid) then smash it up.
