bride and a groom are called up to the Torah or the aufruf. Aside

Candy and raisins are thrown to wish the couple a sweet and fruitful life. Children collect the goodies and gain a sense of the sweet potential of marriage.

Hosting an after-service Kiddush or Oneg Shabbat is a way to share
a couple's happiness with the entire congregation. In years gone by, the portion of Isaac and Rebeccas betrothal was read at the aufruf.
