Definition: Soft-ball stage refers to a specific temperature range when cooking sugar syrups. Soft-Ball Stage occurs at 235-245 degrees. This stage can be determined by dropping a spoonful of hot syrup into a bowl of very cold water. In the water, use your fingers to gather the cooled syrup into a ball. If it has reached soft-ball stage, the syrup easily forms a ball while in the cold water, but flattens once removed from the water.
