Charoset

Charoset, haroset, or charoises is a sweet, dark-colored mixture of finely chopped fruits and nuts eaten at the Passover Seder. According to the Talmud, its color and texture are meant to recall mortar (or mud used to make adobe bricks), which the Israelites used when they were enslaved in Ancient Egypt, as mentioned in Tractate Pesahim 116a of the Talmud. The word comes from the Hebrew word for clay (Hebrew: חֶרֶס, romanized: ḥéres). Charoset is one of the symbolic foods on the Passover Seder Plate. After reciting the blessings, and eating first maror dipped in charoset and then a matzah "Hillel sandwich" (with two matzot) combining charoset and maror, people often eat the remainder spread on matzah. Charoset is mentioned in the Mishna in connection with the items placed on the Passover table: "unleavened bread and lettuce and charoset". Some say it can be traced back to the custom of symposia in ancient Greece, where philosophical discussions were accompanied by drinking large quantities of wine and consuming foods dipped into mixtures of pounded nuts and spices.
