I'm always asked to share this recipe, and people are often surprised to see how similar the ingredients are to their own recipe. While the ingredients may be similar to other posted recipes, the technique is the key to this outstanding potato salad. The specific ingredients are important, too. Russets absorb the flavors best, but don't hold their shape well. Dicing them after they are cold, and folding the other ingredients in gently, takes care of that problem. Don't skimp on the mayo and other dressing ingredients. The potatoes will absorb a lot of moisture, and you want a creamy salad. Another key to flavor and texture is the very fine chopping of the onion, celery and pickle. You want the flavors to disperse throughout the whole dish, but when you take a bite, you want to bite into potato, not an onion chunk. For smaller apetites and crowds, you can halve the quantity easily. In Louisiana and other states where they serve Cajun food, potato salad is often served with gumbo.
