המן־טאַשן

Probably from מאָן (mon, “poppy seed”) +‎ טאַש (tash, “pocket”), altered to refer to המן (homen, “Haman”). The first element is from Middle High German mahe, from Old High German maho (“poppy”).

     אָבער פֿון פּורים האַלט פֿון קינדווײַז אָן, צוליב די המן־טאַשן. איך האָב ליב נאָר אַזעלכע המן־טאַשן, וואָס זײַנען מיט מאָן.

     ober fun purim halt fun kindvayz on, tsulib di homen-tashn. ikh hob lib nor azelkhe homen-tashn, vos zaynen mit mon.

     But Purim lasts from childhood on, because of the hamentaschen. I only love the kind of hamantaschen made with poppy.
