Potato salad

Creamy and tangy, with a soft, starchy bite from the potatoes.

Lens analyzed

Potato salad is a cold side dish of boiled, cubed potatoes bound with mayonnaise, mustard, or a vinegar dressing, often mixed with celery, onion, egg, or pickles. Styles vary widely by region — creamy mayonnaise-based versions dominate in the United States, while German-style versions lean vinegar-forward and are served warm.

Where it comes from

Potato salad traveled to North America with German immigrants in the 19th century, who brought a warm, vinegar-based version that later gave way to the cold, mayonnaise-heavy style now common at cookouts and delis. It remains a fixture of summer picnics and holiday spreads across the continent.

Buying it

Check the deli container for a recent date, since mayonnaise-based salads are more perishable than most sides. Look for potato chunks that hold their shape rather than turning mushy, a sign of overcooking.

Storing it

Keep potato salad refrigerated at all times and eat it within about four days; don't leave it out at room temperature for long, since the mayonnaise base spoils quickly.

Keeps about 4 days in the fridge.
