Cooking Basics

Potatoes - soaking in water

Once cut, the starch in potatoes causes them to turn brown due to the process of oxidation. To avoid this soak cut potatoes in cold water. By doing so you will also be able to remove any starch on the surface and prepare less-starchy dishes. Completely cover in cold water and soak for about 10 minutes. Changing the water halfway through is not necessary.
