When adding liquid constitutes kneading (lisha) — does adding water alone create liability?
Synopsis
A fundamental Tannaic dispute: Rabbi holds that adding water to flour constitutes kneading and creates liability. R' Yosi b. R' Yehuda holds one is not liable until actually mixing/kneading. The Rif, Rambam, and Rosh rule like R' Yosi (adding water alone is not kneading). The Sefer HaTerumah, Sma'g, and Sma'k rule like Rabbi (adding water alone is kneading).
