Candy Thermometer
Be sure to use a thermometer specifically designed for candy-making or deep-frying. Thermometer should be able to register temperatures up to 400°F. To check for accuracy before using, let thermometer stand in boiling water 5 min. Thermometer should register 212°F. Any deviance from this temperature needs to be taken into account when testing for candy doneness.
Cooking Know-How
If you don't have a candy thermometer, remove a small amount of boiled sugar mixture and add to a cup of cold water. If the sugar mixture forms a ball, then candy should be at the proper temperature (246°F).
Substitute
