How to determine polarity when no cord is attached

I have a small hand held electric appliance that had a badly twisted cord (two wire 110VAC). I determined to replace the cord. I cut the cord. I sat the project aside. I had put the original cord in the trash in the meantime, and it was gone. Can you see where this is going already? Later I opened the appliance and unsoldered the remaining cord at the circuit board. I set the project aside again. Later I purchased a replacement cord, actually a three foot extension cord which I intended to use as a replacement cord. I then realized that the original cord had-had a polarized plug, same as the extension cord I intended to replace it with. Not having any part of the original cord to guide me, how do I determine the correct polarity so I won't wire it wrong?
