My water comes from a well and sits in the tank in the water pressure
system. Unless I flush with 5 gallons, it is more likely to be room
temperature. From my experience I think that is good enough. Putting a
couple tablespoons of water into three cups of flour and shortening is
going to warm up the water instantly anyway. The important thing is to
use at least cool, not hot water.
