# [[Dash]] includes removing any earth-grown food from its natural shell or attachment.<ref>39 Melachos (Rabbi Ribiat, vol 2, pg 317) based on the explanation of Rabbeinu Chananel (Shabbos 74a).
<br /> The Gemara Shabbos (75a) records a dispute between Rebbi Yehuda and the Chachamim whether the Melacha of Dosh only applies to giduley karka, meaning things that grow in the ground. The Rambam (hilchos Shabbos 8:7) rules like the Chachamim that mi’d’oraisa it only applies to giduley karka, and this is the opinion of most of the Rishonim. </ref>
==In the Mishkan==
# According to most Rishonim, the melacha of Dosh was done in the Mishkan by threshing the seeds from their shells so that they could be used for the dyes.<ref> 39 Melachos, vol. 2, pg. 315. The Eglei Tal (Introduction #1) quotes the opinion of some Rishonim who maintained that Dosh was done in preparation for the bread that was needed in the Mishkan, in which the case the melacha was removing the grain kernels from their chaff and stalk (39 Melachos, vol. 2, pg. 315). </ref>
