Bureom

In Korea, bureom (부럼) is a collection of various kinds of nuts such as peanuts, walnuts, pine nuts, chestnuts, and gingko nuts. It is one of the most popular and traditional food during the Daeboreum (literally: "Great Full Moon"), a Korean holiday that celebrates the first full moon of the new year of the lunar Korean calendar. It is believed that to crack a nut in your mouth early in the morning on Daeboreum's day will help strengthen teeth, avoid allergies, prevent boils, and bring good luck for the coming year.
