Hard-boiled candies made by the vacuum cooking process include stick candy, lemon drops and horehound drops. Open-fire candy, like molasses taffy and cream taffy, is cooked in open kettles and then pulled. Pan work candies include nuts and other candies like jelly beans and sugar-coated almonds, made by coating with sugar in revolving copper kettles. Gum work candy is cooked in large kettles fashioned for melting and molded, dried and sugared like gum drops. They are soaked for a time in sugar syrup to allow crystals to form.
