How can I determine when my candy has reached the soft ball stage during the cooking process?

To determine when your candy has reached the soft ball stage during cooking, use a candy thermometer to measure the temperature of the candy mixture. The soft ball stage is reached when the temperature reads between 235-240 degrees Fahrenheit. You can also perform a cold water test by dropping a small amount of the candy mixture into cold water, and if it forms a soft, pliable ball, it has reached the soft ball stage.
