Chateau potatoes: Potatoes turned into a barrel shape, then blanched in boiling water, drained then refreshed in cold water, then cooked in the oven.
You can, but you don't have to. Young potatoes with thin skin are especially nice scrubbed but unpeeled. If you are baking them, you must leave the skin on, but boiling, frying, or roasting--it's up to you. (thanks that helps)
The only time I'm sure it noticably effects what your cooking is when you boil potatoes (or any other thick root vegetable). If you start with hot water when boiling potatoes they cook too fast on the outside and get mushy before the middle is cooked. Starting with cold water lets the entire piece of potato get hot along with the water and it cooks through evenly. The general thought here is to use water that you would drink. You would never drink water from your hot water heater.
Start your potatoes in cold water, bring them to a boil and reduce your temperature to medium (you get less boil over that way). Check for doneness (when a fork inserted into a potato enters easily). Drain and serve.
Mashed Potatoes!!About 20 minutes, depending on the size of your potatoes. Start off by putting the potatoes on in cold water (root vegetables should always start in cold water, other vegetables in boiling water). The way to test their doneness is to insert a sharp knife into a few of your potatoes and lift them up out of the water. If they fall off the knife, they're done.
They will cook more evenly if you start them in cold water. This way the whole potato heats up with the water so the outside doesn't cook so much faster than the center.
Start with potatoes - cut into even size pieces - covered with cold salted water. The water should only be on high heat until it starts to boil. Once it boils, reduce heat slightly so potatoes boil gently. Check for "doneness" with a fork. Boiling potatoes on high may cause the results mentioned - mushy outsides with still firm insides or by the time the insides are cooked correctly, the outsides are overcooked and falling apart.
Sodium chloride is also soluble in boiling water.
They are the same. When cold water heats up and bubbles that means it is boiling.
It freeze in cold and disolve in boilng
cold water heating up to its boiling point a physical change or a chemical change
It requires water and oxygen. Cold, lukewarm, or boiling water will do it. Boiling can introduce some other types of errosion/corrosion, also.
