You will work it out Belle, each time you make something you will think of a better way next time.  I never cook my potatoes in the bowl with milk, always in the steaming basket with boiling water below.  I found it burnt the bottom of the bowl with milk and I hate having to do extra cleaning work!  Do you have a thermosaver for keeping food hot if one part of the meal cooks before the other?  They are great for that.
