Steaming preserves texture and prevents waterlogged spuds, which is ideal for potato salads. Choose waxy or new potatoes that hold their shape well. Cut into uniform sizes so they cook evenly; baby potatoes can be steamed whole.
Steaming basics:
Advantages of steaming over boiling include less leaching of flavor and nutrients, and a firmer exterior that holds dressings better. Once tender, transfer potatoes to a bowl and season while warm so they absorb flavors such as vinegar, oil, mustard, herbs, and salt.
Dressing and assembly tips:
Avoid sogginess by not overcooking. If preparing ahead, undercook slightly and finish cooking when reheating briefly; alternatively, dress just before serving. Proper steaming yields tender, intact potatoes that make the best base for any potato salad style.
