Every cookbook I have read says that you should use COLD water when you are going to boil something (like noodles in a pot). Why not HOT water? Does anyone have an answer?

I think it may have something to do with water softeners, and what they put *IN* to the water (I know, they're supposed to remove minerals, but they do put something else in....I can't rinse my hair in pure hot, as it is far to slimy). I find that hot water tastes funny, too. =shp

Why not HOT water? Does anyone > have an answer? If you think about where hot water comes from you get the answer. Hot water is produced in a large tank that is anywhere from new to 20 years old. All of the salts and other impurities that are found in your local drinking water are concentrated in the tank. Some day try an experiment: Take a glass of water from the cold tap and a glass from the hot tap and put them in the refridge until cold. See if you can taste the difference. If you cant taste it, dont worry about it. My guess is tha there will be a difference. - Andy Bindman

You use cold water to boil to make tea because it has more air dissolved in it than hot water does, don't know about general case. P.

If such oxidize they could add undesirable contaminants to the water.

GINO the chemist here, with the answer Minerals have a variable solubility in water, and a particularly lousy taste. (or at least not a particularly good one.) The solubility of just about anything in water (or any other solvent for that matter) goes up with temperature. Sooooo COLD water has less minerals and other nasties in it than hot water. Not a particularly difficult or esoteric thing. GINO

Water softeners add sodium, and make the water slightly acidic.

Does anyone have an answer? *** REPLACE YOUR ASTERISKS NOW *** The way my mom explained it, you never know what goes on inside a water heater, and for any cooking you want to use the water just as it comes out of the ground (or reservoir or whatever). Just pure, clean fresh water, not some that's had the bejeesus heated out of it for who knows how long. I mean, there might be molecules in their that have been roaming around the tank for WEEKS! And by the way, you can believe my mom: she's the world's greatest cook, having invented gravy and the easy way to peel an orange. She also taught all her sons the CORRECT way to boil water - zap it!

Summary: Expires: Sender: Followup-To: Distribution: Keywords: Why start with cold water when you're going to boil it for cooking? My mother used to tell me that old water heaters would collect crud at the bottom, which would get sucked out if water was drawn when the heater was low on water. I hope that it usually doesn't make any difference with "modern" water heaters; certainly it doesn't if you have a continuous flow heater. j

Sooooo > COLD water has less minerals and other nasties in it than hot water. > > Not a particularly difficult or esoteric thing. > > GINO Gino, I have a question. If there are more minerals disolved in hot water, they must come from somewhere? Given that every water heater I've ever had has died due to DEPOSITS of minerals in the tank (despite careful and periodic flushing), it seems to me that the net flow of minerals in my tank is positive, in the sense that they come into the tank, and then precipitate into the tank. Given this, I propose that there cannot be MORE minerals in the hot water, since one has (input minerals) - (minerals deposited) coming out of the tank. <The tanks don't seem to be dissolving, and that's the only other possible source of minerals...> Now, then, all of the dissolved air is generally eliminated, mostly (I understand) by reaction with other disolved minerals, thus leading to FLAT tasting water. This is the reason MY mother always gave me for using cold water. It also shows why that pouring the HOT water through an aeriator and letting it hit the pot hard also seems to make tea taste better.

I once did a taste test making tea with water starting from hot and cold water, and there was indeed a noticable difference. The people I served it to also noticed the difference, and I didn't tell them what it was. (They thought it was a different blend of tea.) Interestingly enough, there was nowhere near a concensus as to which tasted *better*. When boiling water for cooking noodles or anything of that sort, I always start with hot water. It is far more energy efficient to let your water heater heat the water than your stove. -paul asente

Two reasons - one myth, one sensible 1. MYTH - water boils faster if you start with cold water. This is the same logic that says that ice freezes faster if you start with hot water. 2. REAL - water taken from the hot water tap may be softened, and therefore may contain salts. Also, in older homes, the water from an old heater may be picking up large quantities of minerals. These may affect the flavour or colour of foods.
