Line a large tin with greaseproof paper.
Add the sugar and Golden syrup to a large pot.
Stir the mixture together, try not to stir again until it is time to add the bicarbonate of soda.
Bring the mixture to a boil and simmer until the mixture turns golden brown, if you have a thermometer make sure you reach 150C. This should take about 3-5 mins.
Take off the heat immediately and add the bicarbonate of soda.
Ensure that the bicarbonate of soda is mixed into the mixture well.
The mixture will foam and rise, don't panic! this is why you picked a large pot.
Pour into your prepared tin and leave to set.
This could take a couple of hours.
Once the mixture has cooled, remove it from the tin and greaseproof paper and using a sharp knife, cut it into shards of sugary tastiness.
