I am considering buying an in-line reverse osmosis (RO) filter for our new house, as #1, I like to drink good water, and #2, I like to brew with good water. Somewhere in between those two, however, is I also like to COOK with good water.
I feel like a water report is like a snapshot of a single point in time, when the composition of the municipal water can change throughout the year to match rainwater pH/composition, so I'm likely going to start building from RO up.
I can't seem to find any information on the webs about cooking (baking, bread-leavening, etc.) with water that is good for brewing, that is, good for brewing after some salt/acid/base additions. The last thing I need is to be adding CaCl to my wife's shortbread cookies.
Will plain RO water work for cooking as well as brewing, or will I need to make similar additions?
