If I use instant mashed potatoes for my potato bread, what do I iuse to replace 1-3/4 cup potato water?
Sorry if this comes over a little curt…


  Is there a liquid substitution for the potato water?


Water. 1:1 ratio.
Check for seasoning.

It won't taste like potato water, but then again instant mash doesn't taste like potato, so it won't really hurt overall.
