I've been making marshmallows for three years now, and I usually like to go online to solve the problems of users about marshmallow machines and how to make fancy marshmallows. Cotton candy has a burnt flavor has nothing to do with the machine sugar dispenser, mainly because the temperature is not controlled properly. The temperature level to rely on their own feel, the easiest way is to start with a small fire, and then each produced a marshmallow and then slowly try to increase the temperature, until satisfied. If the heat is too low, the candy dispenser won't produce any candy, so take your time to figure it out. Remember, there is a burnt taste, the reason is that the fire is too high, the color of the sugar made a little yellow.
