[Modernist Cuisine] Baked Potato Broth (2•309)

[Anonymous Modernist 5538]

I just got the book and the Baked Potato Broth seems like a good place to dip my toes in the water. I would like a little clarification on how to decant the potato juice from starch residue. All it says is 300g from 700g of potatoes.

It is done in a refrigerator over night. Allow the starch to fall to the bottom, then pour the juice off the top, being careful not to agitate it. It's best to use a taller, narrower container for that reason.

Good thing I saw this post as I was in the middle of making it, have yet to juice the potatoes but that leads me into another question. It also asks to add an additional 300 g of water. Does one need the additional water if the final yield is 300 g? Seems to me the yield will be around 600 g?

Any help would be more than appreciated.

Just figured it out... The dehydrated skins need that additional water to rehydrate.
