A hamantash (also spelled hamentasch, homentash, homentasch, (h)umentash, pluralized with -en or -n; Yiddish המן־טאַש) is a pastry in Ashkenazi Jewish cuisine recognizable for its three-cornered shape. It is eaten during the Jewish holiday of Purim. The traditional filling is made with poppy seeds, but they are also made with many different flavors, including prunes, nut, date, apricot, fruit preserves, chocolate, or even caramel or cheese.
Hamantashen are generally made by rolling the dough thin, cutting it into circles (of various sizes), placing filling in the center, and folding in three sides. The dough may be a cookie dough with orange juice added, citrus zest added, or a yeast dough.
