Line a baking tray at least 2cm deep with greaseproof paper.
Bring the sugar and golden syrup to the boil in a saucepan over a high heat. Allow to simmer for 5 to 10 minutes until golden brown.
Remove the pan from the heat and add the bicarbonate of soda. Quickly mix and once the mixture has foamed up, immediately transfer to the tray and spread out a little. Allow to cool completely before breaking up and enjoying.
It is advisable to not use your best saucepans for recipes that require the boiling of sugar.
