<p class="MsoNormal" style="margin: 0cm 0cm 10pt;"><span style="mso-ansi-language: EN-US;" lang="EN-US"><span style="font-size: small;"><span style="font-family: Times New Roman;">Although the vast majority of Jews in the world do not regard potatoes as kitniyos and eat them on Pesach, there are opinions which rule otherwise. The community of Padua forbade the eating of potatoes during Pesach since they regarded them as kitniyos. The author of the Chayei Odom in his additions/commentary <span style="mso-spacerun: yes;">&nbsp;</span>Nishmas Odom [hilchos Pesach responsa 20] states that <span style="mso-spacerun: yes;">&nbsp;</span>in the years 5531-2 (1771-2) there was a famine in Germany<span style="mso-spacerun: yes;">&nbsp; </span>and the Beth Din permitted the eating of potatoes, because in Germany they did not eat them on Pesach since flour was made from potatoes. The Pri Megadim, [Mishbetzos Zahav<span style="mso-spacerun: yes;">&nbsp; </span>Orach Chaim 453:1] who lived in Berlin, also mentions the opinion that potatoes are kitniyos, but in a more indirect manner.</span></span></span></p>
