This sauce comes from a popular Olivier salad which is a traditional salad dish in Russian cuisine, which is also popular in many other European countries, Iran, Israel, Mongolia and throughout Latin America. In different modern recipes, it is usually made with diced boiled potatoes, carrots, brined dill pickles, green peas, eggs, celeriac, onions, diced boiled chicken (or sometimes ham or bologna sausage), tart apples, with salt, pepper, and mustard added to enhance flavor, dressed with mayonnaise. In many countries, the dish is commonly referred to as Russian salad, although this term can connote vinegret instead. A variation called Stolichny salad exists, and is also popular in Russian cuisine.
