The consistency of the charoset is intended to remind those participating in the Seder of the bricks and mortar their ancestors made as slaves in Ancient Egypt.  One of the romantic takes on charoset is the proposed by Rabbi Levi in the Talmud. He taught that charoset is a reminder of the apple orchards when the Jewish women would go to give birth in order that the Egyptians would not be aware of the newborn Jewish baby.  Also, it referred to the practice of Jewish women, whose husbands came home at night too exhausted to have sex, who would meet their husbands in the apple orchards during their lunch breaks.
