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.
You can cook one potato or you can cook many potatoes to make mashed potatoes. It depends on how many people you want to feed, and how many can potatoes fit in your pot.
Make sure all the potatoes are fully covered by water. It is important to cook them long enough so that a knife or fork can easily be pushed through the potato otherwise mashing will be difficult and you may be left with unmashed potato pieces.
Boil for 20 minutes in salted water. A little less in unsalted.
With real potatoes and water boiling and potatoes cut up about 30 minutes.
For most potatoes, cut into chunks, and depending on the size of the chunks, they should be done enough to MASH in 20 to 30 minutes.

Most Chefs and home cooks recommend Russet potatoes for mashing, as they give the best flavor and texture. However, most any potatoes may be used. I have had delicious Alaskan Golden mashed potatoes, as well as new Red potatoes. But my favorite is still the Russet. Note: Potatoes called 'baking potatoes,' do not usually cook down to a soft texture, and therefore are not as nice to use as other potatoes.
White potatoes do not taste good after they have been frozen. You will notice a change in texture, lack of flavor and the potatoes lose nutrients. Mashed potatoes are so easy and quick to prepare that it is best to prepare eat them fresh. They are fine refrigerated for a couple of days.
No, of course not. I can't give you a long drawn out answer but it is definitely not.
No. ----- You really didn't cook the potatoes long enough if they are still crunchy.
Boil baby red potatoes for 15-20 minutes. Make sure to stick them with a fork, the potato should slide off the fork.
Cut the potatoes into approx. 1 inch cube. If you do this they should only need to boil 15 minutes. If you have the pieces bigger, then it will take longer.

until they are soft - around 10 minutes will usually do it. Keep the pan uncovered while you boil them .
When I make sweet potato pie I bake the potatoes for 45 to 55 minutes. Or until soft on the inside. Soft enough to pierce with a fork. Or you can boil them for 15 to 20 minutes. Just do as you do with regular potatoes. Boil until you can pierce with a fork and it's soft enough to fall apart. But not too soft to be really mushy.
Yes, otherwise you would have to roast the potatoes for a very long time before they're done.
Bacteria. Specifically S.pyogenes. This bacteria is present in the environment, and loves to grow on the starch in potatoes and rice. Don't leave your potatoes out of the fridge uncovred for too long, and definitely do not eat potatoes that have been in the fridge for more than a week. i won't even eat refrigerated mashed potatoes after 3 days.Other bacteria will also infest mashed potatoes if you put dairy in it, and the dairy will sour just as milk does after staying in the fridge for too long. No more than three days storage for potatoes with dairy. When you reheat do it in the oven or stove top. reheating potatoes in the microwave typically does not keep them hot enough for long enough to kill the bacteria.The good news is majority of the "food poisoning" you would get from typical potato bacterias would only last 12-24 hours...
