People associate apples with teachers is the tradition from the 16th century until 18th century in various countries including Denmark and America, in which parents pay educators with foods like fruits. During this time, teachers do not receive enough salary to sustain the cost of living in their places. To help them with their basic needs, parents give the teachers of their children potatoes and apples. During these centuries, apples are considered special and expensive because these fruits are difficult to plant, cultivate and harvest. To compensate the efforts of educators and to make them feel special, parents pay them with different varieties of the fruit.
