Is one who cuts vegetables finely on Shabbat liable for grinding?
Synopsis
The Mechaber rules that cutting vegetables finely constitutes the melacha of grinding. Major dispute exists among Rishonim: Rashi and Rambam hold grinding applies to vegetables, Tosafos and Rosh hold it does not apply to food items at all, and the Rashba/Ran hold it is only prohibited when cutting for later but permitted when cutting to eat immediately.
