What is a difference between oil and flour?

difference

Explanation:

Calling for a "well greased/oiled bowl" is incorrect to me. Using a small amount of oil as lubrication is a good idea, as it stops the dough sticking to the bowl, and it conditions the dough as well. Adding flour is something many of us try to avoid at this stage, as it just dries up the dough. Jeff's call to keep the dough covered is important to this end too.
