How Do You Extract Starch from Potatoes?

What happens when you soak potatoes in salt water?

Salt is the key here. Water will move from an area of less salt to more salt (more water to less water), and so when the potato is placed in the salt water, all the water that is inside the potato (yes, plants have a lot of water inside of them, that's what gives a plant it's structure) moves out by osmosis.

Why do you Soak potatoes in water before frying?

Frying fresh-cut potatoes.
Soaking peeled, washed and cut fries in cold water overnight removes excess potato starch, which prevents fries from sticking together and helps achieve maximum crispness.
