Choosing the right potato is the first step. Waxy varieties such as red potatoes, fingerlings, or new potatoes hold their shape much better than starchy Russets, which tend to disintegrate. Peel only if necessary—skins help maintain structure during cooking.
Cut evenly and start in cold water. Chop potatoes into uniform pieces so they cook at the same rate. Place them in a pot, cover with cold water, and add salt. Starting cold prevents the outside from overcooking while the center finishes. Bring to a gentle simmer rather than a rolling boil; vigorous bubbling can jostle pieces and break them down.
Guidelines to follow:
Avoid overcooking. Check doneness by piercing with a fork; it should slide in with slight resistance. Drain immediately when done and cool quickly under cold running water if you need them cold for salads—this stops the cooking. For hot preparations, drain well and let excess moisture evaporate before dressing.
Tips for fragile situations:
Following these simple rules will keep pieces intact and presentable for salads, stews, and composed plates.
