Charoseth is one of the symbolic foods of the Passover Festive Meal (Seder). The significance of eating charoseth is to remind us today of the mortar used by the Jewish people, when they were enslaved by Pharoah in Egypt. Each group of Jews has its own type of charoseth. The recipe below is Ashkenazic; whereas other charoseth recipes might be made from dates, oranges, raisins, figs, etc., spiced in many different ways. After the seder, my family enjoys charoseth as a spread to use on matzo.
Blend all ingredients in a food processor or blender until almost smooth. This is enough for 24 persons (one night at the Reingolds' house).
