In the early 1980s, she began the custom of including an orange on the Seder plate. This custom is often falsely explained as having arisen in response to a man who confronted a Jewish feminist who was giving a speech and opposed the right of women to become rabbis, supposedly declaring that women had as much place on the bimah as an orange had on the seder plate. However, Susannah Heschel has explained it as a symbol of the fruitfulness of all Jews, including women and gay people. After hearing that some college students were placing crusts of bread on their seder plates as a protest against the exclusion of homosexuals from Judaism, Heschel substituted the fruit (originally a tangerine) on the plate instead. Today, there are seder plates made with seven spots, an extra for the orange on the seder plate, such as Michael Aram's Pomegranate Seder Plate.
