Menachot 57: When are Prohibitions Prohibitions?

The rabbis consider actions which may or may not be prohibited, particularly those that are affected by special guidelines.  On Shabbat, are the following actions disqualified?

• roasting one side of the meat without turning it over
• drilling two or three holes

When preparing the meal offering, are the following actions disqualified?

• using leaven as part of the meal offering without turning it over
• compared with leaven in liquid (libations) or dry ingredients in shewbread or other offerings

The rabbis consider many details in each case and compare them with other known transgressions.  They look at differences between sacred and non-sacred items, wet and dry items, and others.
