The length of time it takes to boil whole potatoes depends on the amount of potatoes and being cooked. A 1 3/4 pound bag of small potatoes cooks in about 15 minutes, once it reaches it reaches its boiling point.
Put the potatoes in a sauce pan, and add enough water so the surface is 2 inches above the spuds. Because of their starch content, some potatoes are better suited for boiling than others if the goal is to maintain the potato's shape, such as for potato salad. New potatoes and round red or white potatoes are low-starch and hold their shape well when boiled. Finnish yellow and Yukon gold have a medium starch content and are satisfactory for boiling. Very starchy potatoes, such as russets, tend to fall apart and are best mashed after boiling. Results may vary.
