Menachot 54: Shabbat Restrictions? Some In-Betweens

We have returned to discussion about which actions might be permitted on Shabbat.  The rabbis consider a number of questions:

• whether a steak cooked on one side before Shabbat may be turned 
• whether one may drill a hole that might be used to create a keyhole 
• whether meal offering might be leavened
• whether vessels used in consecration were themselves consecrated fully
• the ingredients used in meal offerings 

The rabbis question some of the "grey" today.  They examine the "what if" that accompanies questions about real life.  An in-between place filled with questions.
