Hilchot Shabbat 20 (losh part 1)

Introduction to losh – is the mlacha defined by adding water or mixing? Workarounds may include changes such as the mixing order, amounts, technique and viscosity. There are workarounds.

Continuation of losh with focus on the application of the workarounds outlined in Part i.

Hilchot Shabbat 22 (Losh part 3)

Review of workarounds to losh (preferred – shesi veruv, finger; less so – slow, weak, change order/viscosity) some things may not be losh at all (adding liquid to preexisting mix, own juice, large pieces). Also discussed – techina egg salad and other practical applications.

Hilchot Shabbat 23 (Maaseh Shabbat 1)

The rules of what benefit you can get from a prohibited mlacha done on shabbat are dependent on: who did the mlacha, was it done bshogeig or bmeizid, is the prohibition rabbinic or torah, is the time delay/prohibition of use a penalty (knas) or an issur hanaa? Is it a makom tazorech and is there any doubt in the application,-bishul-1)/

Hilchot Shabbat 24 (Maaseh Shabbat 2, Bishul 1)

Hilchot Shabbat 25 (Bishul part 2)

Begins with discussion of the duraita nature of bishul in microwaves and induction stoves (including bishul akum).

Then discussion of the status of dud shemesh (is it toldot chama or toldot or?) salting (not generally bishul) and bishul achar bishul (mostly lchumra).

Hilchot Shabbat 26 (Bishul part 3)

Is there bishul achar bishul with a davar lach (TBD)? Topics include: status of microwave and induction cooking, how cooled off is cooled off, and what portion must be lach?

Finishing up bishul achar bishul – how do tzli, tzli kedar, afia and tigun interact with bishul (before or after)?

Hilchot Shabbat shiur 28 (Bishul part 5)

Defining kli rishon and especially kli sheni. While we generally say kli sheini isn’t mvashel, there are exceptions. Do we view it as physical reality or normative law? Is making something to prepare forlachila also makeh bpatish? (no) What are kalei bishul and how are they treated?

Hilchot Shabbat 29 (Bishul part 6)

Practical applications of differing opinions on when kli sheini and shlishi may be mvashel. General rule of kalei bishul applied for spices, tea, coffee ….

Hot into cold bishul and vv (especially liquids) – factors include type of kli (ambatya, sefel, meicham) level of kli (rishon, irui, sheni) and volume liquids/% coverage.

I’m still fascinated by the question of whether kli sheini eino mvashel is a normative (absolute) rule or a physical observation subject to rebuttal in specific cases).
