No leaven (hametz) may be eaten during the Passover festival. The festival is preceded by a
ritual in which the house is searched for leaven. The leavened food may be burned or sold to
non-Jews and repurchased after the holiday week.

The search for leaven is conducted with a feather and candle. This artistic interpretation of
the ritual symbolically ensures the crushing of all unfound leaven into the soil.
