There is a widespread custom that during Adar, people make and bakers bake
three cornered filled cookies called Hamantashen.
One year, on the day before Purim, Rav Yaakov Berlin, the father of the
famous Rabbi Naftoli Berlin (the Netziv), went to the market to purchase this
special treat in honor of Purim. He went from baker to baker, but no
Hamantashen were to be found. He found this situation to be quite odd, and he
therefore asked one of the bakers why no one had any Hamantashen. He was
informed that the year had been one of a serious drought. The price of flour
skyrocketed, and bakers were only able to afford flour for the Shabbos
challah. Flour for any other purpose, including Hamantashen, was not even
considered because it was so expensive.
As soon as Rav Berlin heard this, he immediately called for all the city's
bakers. Once they were assembled he presented them with a large sum of money.
Rav Berlin told them that the money was to be used to purchase flour so that
they could bake Hamantashen. Why did Rav Berlin feel so strongly about having
Hamantashen available? He explained that these special cookies had for
generations been consumed during Adar. Being that it was a long standing
tradition to have Hamantashen, and it is forbidden to annul customs,
Hamantashen must be baked.
Rav Berlin then explained how Hamantashen got their name. In Megillas Esther,
we find that Achashverosh had never rewarded Mordechai for his role in saving
the king from a plotted assassination. However, one night, "the sleep of the
king was disturbed." On that night, Achashverosh was reminded that Mordechai
had not been rewarded, and he ordered Haman to parade Mordechai around in
royal fashion. This marked the beginning of the salvation of the Jews from
the murderous scheme of Haman. The Yalkut Shimoni tells us that Achashverosh
was not the only one who had his slumber disturbed that night. On that night,
the "slumber" of our three forefathers Abraham, Yitzchok, and Yaakov was
disturbed because of the evil that was to befall the Jews. They pleaded with
G-d to spare the Jewish people from destruction. In the merit of the
forefathers, Haman's power weakened. When combined with the prayers and
repentance of the nation, this merit helped saved the people from
destruction. The word for "weaken" in Hebrew is "Tash." Thus, the three
cornered cookie, with each corner representing one forefather, is named
"Haman tash," "Haman was weakened." The presence of this highly symbolic
cookie was a long standing custom, and therefore, Rav Berlin explained, the
custom must continue.
When we munch on our Hamantashen, we should make sure that we properly digest
the reminder contained within!
