Then stir with a wooden spatula. After a few seconds the mixture should become grainy.If this does not happen immediately it is because the sugar has not reached 120°C (250°F) yet. Don't worry, just keep stirring for a while longer until the change occurs.
When the mixture has turned grainy (like in the photo), stop stirring, remove from the heat and leave to cool.
