from Hilchos Shabbos | Rabbi Meir Finkelstein (Yeshivat Kerem B'Yavneh) · host Yeshivat Kerem B'Yavneh
AI-Generated Summary (AI can be inaccurate. Check important information): 1. *Tea in a *Kli Sheni** — *Rav Chaim Kanievsky** permits making tea in a *kli sheni*, arguing that tea leaves are categorized as *tavlin* (spices), which the *Mishna* (*Shabbos* 42b) teaches do not cook in a *kli sheni*. 2. *The Essence Solution* — The *Mishnah Berurah* (*Siman* 318:39) suggests preparing "tea essence" before *Shabbos* to avoid *bishul*. On *Shabbos*, one may add this liquid essence to a *kli sheni* of hot water, relying on the view that *bishul achar bishul* (cooking after cooking) for liquids is not a concern in a *kli sheni*. 3. *Instant Coffee Status* — Since instant coffee is pre-cooked during manufacturing, *Rav Moshe Feinstein* permits making it even in a *kli rishon* (*Iggros Moshe* O.C. 4:74); however, due to concerns that it completely liquefies, many follow the *Mishnah Berurah’s* stringency regarding salt and use a *kli sheni*. 4. *Residue and Droplets* — When refilling a cup, *Rav Moshe Feinstein* is lenient regarding the residual cold droplets from the first cup, while others suggest the droplets are *batul* (nullified) to the new hot water or that the act is a *psik reisha d'lo nicha lei* (an unintended, non-beneficial result). 5. *Solids that Liquefy* — A central principle in *Hilchos Bishul* is that a solid which melts (like fat in an *Inpanada*) is judged by its initial state as a solid; thus, *ein bishul achar bishul* applies despite the change in form (*Shulchan Aruch* 318:16). 6. *"Via" and Micro-grounds* — For specialty coffees containing raw micro-ground beans, using a *kli shlishi* is recommended to avoid *bishul mamash*, as the ground beans have never been cooked. 7. ***Borer* in Brewing** — Pouring hot water over coffee grounds in a filter does not violate *borer* (sorting), because the process starts and ends without a *ta'aroves* (mixture) of solids and liquids, following the *Mishnah Berurah's* ruling on straining wine (*Siman* 319:33).
