100g caster sugar
3 tablespoons golden syrup
1 and a half teaspoons bicarbonate of soda
Mix sugar and syrup in a heavy-based saucepan.
Over a medium heat, melt and bring to the boil until a deep golden colour, this should take 2 to 4 minutes.
Remove from the heat, whisk in the bicarbonate and quickly pour onto a lined tray.
Leave to set for 20 minutes, drizzle with chocolate if desired.
