Non-Deep Fried Turkey Kitchen fire

So there we were, cooking away, to make a complete Thanksgiving meal.  We had company over, and were trying to hit a meal timeline.  The kitchen was quite busy.  The kids were helping with specific dishes.  The water and butter for the stuffing boiled over.  The burner was used for cooking potatoes next.  During the potato water boiling, the butter water residue in the burner drip-pan caught fire.  Knowing that grease was involved, I advised my wife to not use water to put it out...  ...which she disregarded--

The fire flared up, and then, in the moment, my wife couldn't remember if baking soda or baking powder were used on a fire, so she poured both.  The fire was quickly extinguished, with no damage to surrounding walls or appliances-- we were lucky.

The kids were talking about the fire for the rest of the evening.  Key learnings:

1.  Do not leave a pot unattended, so it won't boil over. 
2.  When a pot boils over, clean out the drip pan before using the burner further.
3.  Prepare a plan, in the event of an unforeseen issue.  Educate others about the plan.
