To achieve the correct results when boiling sugar, it’s essential to use a sugar thermometer.
Check the accuracy of your thermometer by placing it in water that has just come to the boil. The boiling point of water should read 100°C, dropping by 1°C at the coast. Warm the bulb by dipping it into hot water before immersing it into the syrup. Hold the thermometer upright and read it at eye level.
