Potato salad is a boiled potato dish that includes a variety of other ingredients. It is generally considered a side dish that accompanies the main course. It is widely believed that potato salad originated in Germany, where it then spread widely throughout Europe and later into European colonies.
American potato salad most likely originated during the nineteenth century from recipes brought to the U.S. by way of German and European immigrants. American-style potato salads are served at room temperature or cold.
A helpful tip is to start the potatoes in cold water before bringing them to a boil. When you put potatoes directly into boiling water, the outside will cook instantly and the inside can take longer, resulting in some hard and soft bits of potato salad. Before removing the potatoes, do not forget to salt the water which will flavor them from the inside out.
