These are the kind you found at the circus or carnival! Not the newer version covered with cramel. ;) Candy thermometer is needed for this, as well as popsicle sticks. The number of apples needed depends on the size of the apples, probably 4 medium ones. The recipe states that each batch candies approximately 1 dozen medium apples. I'm not sure I trust that. Cook time depends on your altitude where you live, heat of your burner, and pot used. NOTE: See review by Canada Goose for helpful hints! Thanks, CG!
