Here is a text and video about the cleansing ritual
which includes the sentence
Once again, purify your left hand. Finally, stand up the ladle and purify the handle with the remaining water.
In this context, is 柄 "handle" pronounced 柄【え】 or 柄【から】 or 柄【つか】?
I tried looking it up in a couple of places and could not figure it out.
