We begin the next melacha, Tochen, grinding. This melacha involves breaking down an item into small parts.

We discuss when cleaning fruits is problematic, and when it is permitted.

We continue our discussion of filtering with liquids that are slightly unclear, and liquids that are very much in need of filtering. We also discuss what can be done to filter in a permitted way, while still avoiding the problem of Borer.

When it comes to filtering, there are three different types of liquids. Those that are clear, those that are somewhat dark, and those that are completely dark. We begin with those that are clear.

Sorting mixtures of items, when not for immediate use, will constitute a problem of borer, separating.

We learn how one can remove bones of meat and fish, and how it would be forbidden.

We discuss the forbidden and permitted circumstances to remove pits and seeds from fruit.

We discuss when a peel is considered secondary and therefore must be removed in the way of eating, as opposed to some peels that are considered part of the food, and may therefore even be removed with a peeler, which is a utensil specifically made for borer.

Separating for immediate use is permitted under the correct circumstances. This concept has broad applications which we discuss at length.

We continue to explore the cases that involve separating with a utensil.
